SF’s $1 Billion Investment in Electric Vehicle Infrastructure Bodes Well for Embedded

EDITORIAL

DECEMBER 2008

by Tom Williams, Editor-in-Chief

I

n what now seems a rather prophetic occurrence, the September issue of RTC ran an editorial titled, “The Network is the Automobile,” which described projects being implemented in Denmark and Israel—and now Australia—to take those countries off the use of oil for automobiles. The main contractor, Palo Alto, California-based Better Place, has designed the overall technology and is in partnership with Renault/Nissan, which has committed to building the first automobiles. Numerous other contractors will supply batteries and other aspects of the system, which includes the electric cars, removable batteries and an intelligent charging network infrastructure.

Just recently, the mayors of San Francisco, Oakland and San Jose, California held a press conference to announce their intention of becoming the electric vehicle capital of the United States.

They are starting an initiative in conjunction with Better Place, backed by $1 billion in investment, to design and build a charging and battery exchange infrastructure in the San Francisco Bay area for sedan-sized electric vehicles.

The mayors, with the backing of California Governor Arnold Schwarzenegger, recognize that government has a role to play along with market forces in the direction of technological development. In concert with the intelligent charging network, the cities have agreed to standardize and expedite their permitting, zoning and tax incentive policies to encourage the development of the infrastructure. The plan is to start designing the network immediately and actually deploy it starting in 2010. By 2012, the goal is to have the network in place so that mass sales of electric vehicles can begin. San Jose, for example, is looking into building charging stations into the posts of street lights.

The key concept of the Better Place approach is that the cars will seat five, get from 0 to 60 mph in 7.3 seconds and not be limited by the charge capacity of the batteries, which today can take them 100 miles. Beyond that, a system of automatic battery exchange stations will allow drivers to drive into a bay resembling a car wash and have their battery automatically exchanged with a fully charged one in less time than it takes to fill a tank with gasoline. Cars have internal GPS systems and voice-activated computers to identify destinations and available charging facilities. RFID technology keeps track of billing because the charges are for electricity used in terms of miles driven. All these things represent enormous opportunities for embedded computing for control systems and networking and more.

If successful, the effort will not stop with the Bay Area.

There are longer-range plans to install infrastructure networks in California’s three other metropolitan areas: Sacramento, Los Angeles and San Diego. These would be linked by a series of exchange stations along the major interstate corridors and the network would organically branch out from there.

The key concept here is intelligent infrastructure—with the emphasis on the word “intelligent.” There will, for example, be times when the power grid might draw power from connected vehicles during peak usage hours. At night, when most cars are parked and charging, is an ideal time to utilize the surplus power from wind generators, which of course run all hours. As the power grid becomes more integrated with the transportation system, and more decentralized as a result of wind power and solar panels on increasing numbers of rooftops, it becomes more intelligent as well—and more in need of embedded computing to distribute power where needed and keep track of the amount used by or contributed from any given customer.

None of this requires any technological breakthroughs. It will, however, engender innovation to improve and optimize the system and to design different vehicles for different market segments. And it will spur the manufacture and sales of vast numbers of semiconductors and embedded modules out of the Silicon Valley segment of the economy along with a revitalization of American manufacturing out of the Detroit segment. This assumes that we don’t want to buy all those cool electric vehicles from France and Japan.

Again, the key word is infrastructure. The automobile industry grew up on an infrastructure of roads, steel and oil. The Internet with e-commerce and all its benefits grew up on an electronic infrastructure. The new age of electric vehicles—which is now to become a reality—will grow up on an infrastructure of heavy industry, digital communications, embedded intelligent control and new sources of clean renewable energy. All these have the common thread that they gain by the use of computer intelligence. So as we start the New Year with what looks like the economy in the tank and the auto industry in meltdown, there is light ahead and it’s an attractive shade of green.

UPDATE: At this writing, Hawaiian Governor Linda Lingle has just announced an agreement with Better Place to build a network consisting of some 50,000 to 100,000 charging stations that will cover the entire state of Hawaii. This is happening, folks!

World’s First Operating System to be Certified to EAL6+ Security Level In what really is a world first, the Integrity-178B operating system from Green Hills Software has been certified by the National Information Assurance Partnership (NIAP) and the U.S. National Security Agency (NSA) to Common Criteria Evaluation Assurance Level 6+ (EAL6+) High Robustness, against the U.S. Government Protection Profile for Separation Kernels in Environments Requiring High Robustness (SKPP). Only an EAL6+ High Robustness operating system is certified to protect classified information and other highvalue resources at risk of attack from hostile and wellfunded attackers.

Many other operating systems are certified to EAL4+ or lower. The Common Criteria security specifications for these products claim “protection against threats of inadvertent or casual attempts to breach the system security.”

Furthermore, Common Criteria states that EAL4 “is the highest level at which it is likely to be economically feasible to retrofit an existing product line.” No other operating system has even begun the stringent EAL6+ NIAP/NSA certification process. The NIAP Common Criteria Evaluation and Validation Scheme site http://www.niap-ccevs.org/cc-scheme/ in_evaluation lists products that have begun a certification process.

Integrity was certified against the Common Criteria’s Separation Kernel Protection Profile (SKPP), whose high robustness designation represents the gold standard for operating system security certification, requiring “security services and mechanisms that provide the most stringent protection and rigorous security countermeasures.” The security gap between EAL4+-certified products and SKPPcertified products is immense: while EAL4+ does not even require examination of the product source code, SKPP requirements include the use of formal methods to mathematically prove the security policies, formal specifications, formal correspondence between design and implementation, complete test coverage of all functional requirements, and penetration testing by the NSA, which has complete access to the source code. The certification of Integrity to the SKPP began in 2005.

Integrity has been certified to meet the following government and industry reliability standards: • DO-178B Level A, the highest level of avionics safety certification granted by the Federal Aviation Administration • FDA Class III, the most life-critical medical devices approved by the Food and Drug Administration • IEC 61508 SIL 3, the highest level industrial safety certification granted to an operating system by TÜV • CMMI Maturity Level 3 for the Integrity software development organization With its open standards, POSIX-conformant interface and ability to host arbitrary general-purpose operating systems, such as Windows and Linux, in virtual machines, Integrity has been certified with the ability to run application software supported by any hosted operating platform, while maintaining the highest level of security for critical components, algorithms, applications and subsystems. Target solutions include safe Internet browsing on corporate PCs; protection of critical enterprise servers; unhackable digital rights management (DRM); and multi-level security for government laptops, desktops, PDAs and servers. An EAL6+ certified operating system represents the level of security required to protect the nation’s critical cyber infrastructure. Critical infrastructure devices and operator computers are increasingly networked, perform critical functions requiring in-field maintenance, and discharge an evolving role requiring in-service software upgrades. Integrity enables computing control and management solutions that cannot be hacked.

In a related move, Green Hills Software has announced that it has formed Integrity Global Security, LLC as a wholly owned subsidiary. The new company will market Integrity secure separation solutions, based on Integrity, the first and only operating system ever to achieve Common Criteria EAL6+ High Robustness certification. The new company’s charter is to use Integrity as the foundation to protect government and corporate cyber assets.

Integrity Global Security offers solutions that close the security gaps and make computing environments secure. Integrity Global Security’s experts apply a methodology called Secure Separation Architecture to create absolutely secure and totally reliable software, including the Integrity operating system, secure call centers, secure PCs, secure Web portals, secure financial transactions and secure PDAs. Integrity Global Security, LLC will be led by chief executive officer David Chandler. surements in open field agricultural applications to remote monitoring sites.

SMALL FORM FACTOR FORUM

The CPU is the Chicken.

No, it’s the Egg. No, it’s the Chicken...

T

he history of popular bus architectures shows that the dominant player in the development of these architectures is the processor manufacturer. Intel has played a key role in all major PC bus architectures—ISA, PCI and PCI Express. The I/O folks mostly come along for the ride. But within the embedded world, bus architectures typically go hand in hand with form factors. And here it has become clear that without active participation by the I/O manufacturers, and the confidence that a robust I/O ecosystem will exist for any new form factor / bus architecture combination, any new specification is doomed. So while processor chip folks will continue to define the signals on the pins and SBC manufacturers integrate new processor / chipset components onto smaller and smaller form factors, the measure you need to look for to determine the longevity of any new form factor / bus specification is how many I/O suppliers are along for the ride.

A look at the history of PC/104 proves revealing. PC/104 was initially conceived as the video expansion solution for EBX form factor SBCs. The integration of dozens of discrete components into the first chipset by Chips and Technologies allowed CPU boards to be built in this tiny form factor. At its peak, the PC/104 Consortium could identify well over 1000 PC/104 products on the market, and at most a few dozen of these were CPUs. The vast majority were I/O cards. And one of the reasons that PC/104 (and ISA) remain so robust to this day is that while CPU technology rolls over every six months or so, I/O technology evolves much more slowly, if at all. There are popular PC/104 I/O cards on the market today that were first introduced over 15 years ago. While CPU designs are driven by how many transistors can fit on the head of a pin and the need to use all that silicon available between the pads, I/O technology is more closely attuned to human speeds—vision, hearing, touch, DAQ, etc. A new super-fast digital I/O card that costs more isn’t going to gain much traction.

The new PCI Express-based form factor / bus specifications may not garner much I/O support initially. First, the I/O players are looking for sockets to fill, and there just aren’t enough embedded PCI Express sockets available to pay for the cost of a new

10

December 2008

design. Secondly, these designs are complex, with high-speed logic requirements, and the high speed provides little benefit to the OEM customer. Perhaps the biggest push behind OEMs to PCI Express-based designs is fear of obsolescence of older ISA and PCI-based SBCs. Third, it just plain takes a long time to build up an ecosystem of a thousand I/O cards.

So, if you can’t really count the I/O cards yet, how do you determine a “safe” SBC solution that will be around in 10-20 years?

Does the specification enable easy migration from current solutions? Can currently available I/O boards be incorporated in the system? Even though the ISA bus is fading away, ISA cards can be enabled easily through bridge devices from the LPC or PCI bus. While bridging from LPC is fairly straightforward, bridging from the PCI bus requires that the SERIRQ (serial IRQ signal) be available on the connector. Since PCI can also be obtained with a bridge from PCI Express, ISA can be obtained from PCI Express with a double bridge implementation—ugly but functional. LPC is much simpler and less costly to work with. Note that while putting an ISA connector on the SBC makes this a very simple transition, it burdens every SBC with the double bridge cost since ISA support (and soon PCI as well) has been eliminated completely from the new generation CPU / chipset components.

Secondly, look for membership of key I/O players in the various consortia. Ask your I/O vendor where they are placing their bets for the future. Finally, look for initial product introductions.

A small form factor SBC with expansion connectors but without any available I/O cards is pretty useless. At least some I/O should be available at the same time the first SBCs are launched.

I/O support is the key to the long-term viability of the new small form factor standards. Even if you don’t need expansion I/O today, the availability of a broad I/O ecosystem will most certainly determine if your new SFF SBC will be available three years from now. You can’t afford not to know the score.

and control equipment to ATM machines and other forms of interactive kiosks and medical devices.

CompactFlash initially emerged as the form factor of choice for embedded systems due to its small footprint, performance, reliability and its adoption as a well-understood industry standard. The initial cost per gigabyte for CompactFlash was very high, limiting adoption to embedded applications where it was crucial to have no moving parts and the ability to withstand extreme temperatures and high shock and vibration. As the cost decreased, demand exploded due to the merits of solid-state storage in many applications.

However, looking to the future, there is a downside to using CompactFlash because of its limited interface compatibility with Parallel ATA (PATA).

Demand also grew for SSD solutions as primary storage in embedded applications that did not require ruggedization or were not deployed in harsh environments.

For these applications, SSDs were attractive for their lower power consumption and long product life in usage models that often required 24/7 “always on” capability. SSDs in 2.5-inch and 1.8-inch form

factors became true drop-in replacements for hard drives in embedded applications that required high endurance, multi-year product deployments of up to 10 years, faster data transfers, less frequent product requalifications and protection from the effects of power anomalies.

Onboard Storage Meets Embedded

Demand for onboard storage that meets designers’ performance, reliability, size, low power, interface, scalability and security requirements has resulted in new SSDs with integrated technologies to match embedded system application requirements. Industrial-grade SSDs are available in a wide range of form factors from 2.5-inch and 1.8-inch drives, to CompactFlash and PC Cards and 40 and 10-pin modules plus new ultra-small modules with no compromise in performance, reliability, scalability and product life. Now that SSDs are viable for onboard storage, embedded system designers can choose from SSD technology that has evolved with faster read/write speeds and that supports popular USB and SATA interfaces, as well as traditional PATA, SD and MMC interfaces (Table 1). Important, too, the latest SSDs are available in capacities that match typical embedded system usage models. These tend to use SSDs for operating system storage, fast boot capabilities, event/error logging, look-up tables, etc. Optimal storage capacity for these functions is well within the capacity range of most SSDs: 512 Mbytes to 32 Gbytes.

Because they only require a fraction of the system power of hard drives, SSDs are an appropriate choice for onboard storage even in the most spaceconstrained designs. Adding to the power and reliability advantages of SSDs, are integrated technologies that prevent drive or data corruption from power anomalies.

The number one cause of storage system field failures is drive corruption from an ungraceful power-down, brownout, power spike or unstable voltage level. When power goes out, the result is often a corrupted drive and ruined data, resulting in costly unscheduled downtime as field technicians reformat drives, reinstall operating systems or return products. New

integrated voltage detection technology in SSDs eliminates drive corruption in the event of a power disturbance adding significantly to system reliability.

Contributing to its high endurance and reliability, solid-state storage technology features robust wear-leveling and error correction code (ECC) algorithms.

In addition, integrated technologies that act as an early warning system to forecast usable life are now standard features on advanced SSDs to virtually eliminate the

Security breaches are on the rise for embedded systems, which means that robust security must also be a crucial feature for SSDs. In the past, system design challenges due to the small footprint and low-power requirements for storage sys-

face. There is also a growing trend in embedded computing to migrate to smaller form factor boards such as Computer-onModules (COMs) where CompactFlash is actually too big for the computing platform. Addressing embedded system demand for an ultra-small advanced storage form factor that supports faster interfaces, SiliconSystems has developed the company’s SiliconDrive II Blade product family, which combines integrated advanced stor-

age technologies with the robustness and locking mechanism of the SiliconBlade Socket (Figure 1).

The SiliconDrive II Blade was designed as an alternative to SD and MMC cards in netcom, embedded, industrial, military and medical applications. More robust, secure and a quarter of the size of a CompactFlash card, it offers improved shock and vibration due to the “lock down” mechanism of the connector. An-

There are a plethora of SSD options available today enabling OEMs to choose the onboard storage solution that matches their chipset, host interface, performance, reliability, power, usage model and security requirements. OEMs have the flexibility to design a wider range of products that match the needs of a variety of markets.

Designers no longer need to work around form factors and interfaces compatible with the chipsets originally designed for consumer applications. Today, there is a good variety of SSD form factor options for onboard storage that offer the high performance, high reliability and long product life needed for the rigors of embedded system applications.

other benefit of the SiliconDrive II Blade is that it is upgradeable in the field for long deployments, unlike chip down solutions that are soldered to the PCB. The new form factor is available in capacities from 512 Mbytes to 4 Gbytes.

Responding to market demand for open standards and the need for second sourcing of products, SiliconSystems has contributed its SiliconDrive II Blade specification to the Small Form Factor Special Interest Group (SFF-SIG) for the purpose of creating an official governing standard. With its growing membership of embedded computing suppliers who are interested in advancing small form factor designs and adoption, the SFF-SIG has formed a working group to develop a specification under the “MiniBlade” name that will define a wide array of storage, communications, GPS and other I/O products. Members of the SFF-SIG will have full access to the MiniBlade specification. The small form factor embedded system market will now have a standardized ultra-small mass storage solution.

To Defrag or Not to Defrag—That Is the Question for SSD Solid-state disks are becoming a popular storage medium in embedded applications. In real use, SSD suffers from file system fragmentation just like HDD. While defragmentation can restore performance, care must be taken not to incur too many write cycles in clearing file and free space fragments.

on. Depending on how you use it, your computer can become sluggish in just weeks or months. The main reason for this aging phenomenon is not in hardware but in software. Or, more precisely, it is file system fragmentation that slows down your computer.

One might say that this is true for HDD because the read/write head needs to position itself to the right place during read/write operation and it takes time to do that. As a file is cut into pieces and stored in different memory area of the HDD, the read/write head travels to the locations of each file piece and spends one seek time to read and write each piece of data. Thus the read/write time naturally multiplies by a factor in proportion to how fragmented the file is. One might then conclude that file fragmentation will not cause a slowdown in an SSD because there is no read/write head and therefore the mechanical seek time is zero. In an SSD, every file tends to be broken up into pieces and stored in different physical locations of the flash memory cells because the logical-to-physical (L2P) mapping used in managing the flash memory seems to scramble the relationship between logical addresses and physical addresses of data. Since everything is done electronically, not mechanically, one might conclude that file fragmentation is not a problem for SSD at all.

The above statements are right about HDD, but only half correct for the SSD

part. It is a misconception that SSD does not suffer from file system fragmentation.

A large part of system slowdown can indeed be attributed to the read/write head spending too much mechanical seek time for highly fragmented files in HDD, and SSD does reduce that to zero. While this is a significant improvement, mechanical seek time only makes up a part of total access time, or I/O time, of any single input/ output request made to the disk. I/O time is the time a computer system takes to complete a request cycle all the way from application, OS and driver down to disk hardware, memory cells, and then back again.

Zero mechanical seek time certainly does not mean zero I/O time. No matter how fast an SSD can be, its I/O time can never be zero. File system fragmentation affects I/O time in an SSD even when the mechanical seek time is zero. To put it another way, the misconception that SSD does not suffer from file fragmentation derives from seeing the performance degradation as a problem of the storage device alone, a problem of whether there is mechanical moving part or not, but not as a problem concerning the system as a whole. The question at issue here is I/O time, not seek time.

Here we must distinguish between two different types of fragmentation under the name “file system fragmentation.” They are file fragmentation and free space fragmentation. File fragmen-

tation is the cause of slow read because the file is stored as a bunch of noncontiguous smaller pieces scattered around. Free space fragmentation, on the other hand, is the cause of slow write. It happens when there is no contiguous free space available for storing a file in one write such that the file system allocates a bunch of noncontiguous smaller slices of free space to store this file in several writes. Free space fragmentation leads to file fragmentation

during write operations. File fragmentation leads to free space fragmentation— this happens when fragmented files are deleted. It is obvious that the two types of fragmentation form a vicious circle.

Kicking seek time out of our equation, one can understand that for an SSD the main factor that causes performance drop is file system fragmentation. This is a problem at the level of file system and MFT table (NTFS), where files become frag-

mented such that one access request for one file turns out to be several or more access requests for pieces of file fragments that make up the file. This “I/O multiplication” effect found in a fragmented file system is particularly noticeable during write cycles.

The reason is the erase-before-write characteristics of NAND flash: data can be written into a memory block only after existing data has been erased. Since the erase/write speed is slow compared to read, a write multiplication due to free space fragmentation can slow down I/O time severely.

Defragmentation Comes to the Rescue

In September, Apacer introduced its first SSD bundled with optimization software to address, among other things, the problem of file system fragmentation.

By applying defragmentation algorithms specially tailored for SSD, the Optimizer software can restore read operation 5.9x faster, write operation 19.5x faster, random read 3.9x faster, and random write 9.0x faster. Notice how file system fragmentation can degrade system performance in this test case. In a severely fragmented file system, sequential read can degrade to the level of random write, and sequential write and random write become extremely sluggish. Here we see to what extent SSD may suffer from file system fragmentation, and how defragmentation can bring performance back (Figure 1).

Now comes a problem. Since the defragmentation routine will move file fragments in trying to consolidate files and free space, it causes additional write operations to the SSD’s NAND flash.

However, NAND flash can only allow for a limited number of erase/write cycles for each memory unit—a lifetime issue. If you write too often, your flash will soon die out. It appears that, by shuffling files, defragmentation will increase the erase counts and shorten the life span of SSD. Indeed, having limited erase/write cycles is an SSD’s weak spot. The problem of how to minimize erase count in flash has been one of the key research areas for flash vendors. It concerns, at the level of memory controller and L2P table, how efficiently the memory controller manages data among memory cells. No matter how good the memory controller may be 1 20Untitled-1 December 2008

in reducing its “write amplification” factor, using whatever kind of wear-leveling algorithms, memory controllers in their present architecture seem incapable of doing anything to cope with the increase of erase/write cycles caused by the I/O multiplication in a fragmented file system.

Thus we face a dilemma. On the one hand, we need to defrag our SSD to improve its performance. On the other hand, we cannot defrag too much lest too many

writes shorten SSD’s longevity. Traditional defragmentation aims to clear all fragments found in a target disk. But this strategy cannot work for SSD because of the life time issue. The solution to this dilemma is certainly one of balance and compromise.

That is, how to devise a defrag strategy that will improve throughput while at the same time not incurring too many erase counts?

It appears that the better defrag strategy is to prevent free space fragmentation

from occurring without being too aggressive in consolidating files. Since free space fragmentation leads to file fragmentation, if free space fragments can be minimized, the chances of creating fragmented files can also be minimized. If such a defragmentation strategy is applied at the initial stage of an SSD, then the file system can be optimally maintained in a less fragmented state. This helps to turn the vicious circle of fragmentation into a virtuous one. On the other hand, by consolidating files only when needed, erase counts used in consolidating files are minimized.

Figure 2 shows a test case done by Apacer where cumulative erase counts of an SSD test sample going through a series of procedures are documented. In this case fragmented free space is artificially created at stage 2 and stage 5. The optimization algorithm is applied at stage 6.

HDBENCH is first run in a fragmented free space at stage 3, and then in an optimized, defragmented, space at stage 7.

Defragmentation does incur erase count increase for 4. Running HDBENCH incurs 4 counts in a fragmented space, but only 1 in a defragmented space. That is, the optimization algorithm reduces HDBENCH erase count from 4 to 1.

Based on the test, we can argue that although optimization will use some erase counts in consolidating fragments, it reduces erase counts incurred by other write activities that are done after it because fragments are already cleared. The total erase counts incurred in the case with optimization are only a fraction more than the total erase counts incurred in the case without optimization. It is as if applying optimization saves a number of erase counts from later write activities only to use them in advance. Since erase counts accumulate differently in different user scenarios, it is conceivable that the total erase counts incurred in the case with optimization can be the same as, or even less than, the total erase counts incurred in the case without optimization. This means a well-designed defrag algorithm can extend an SSD’s life span.

Sentiris AV1: Toward an Obsolescence-Proof GPU Sentiris AV1, developed by Quantum3D, Inc., was born out of a desire to meet the needs of the safetycritical market. The task here, insofar as safety-critical certification is concerned, became discovering a way to build a next-generation XMC that could achieve certification via its firmware.

This would enable upgrades as the market’s needs change.

To develop this “obsolescence-proof” GPU, Sentiris AV1 leverages an FPGAbased video and graphics processing core instead of the traditional approach of using dedicated graphics processing units (GPUs). The XMC Mezzanine Card contains a Vir tex 5 FXT FPGA that runs the core GPU engine, PCI Express communication path and video back-end features. The XMC also contains a wide memor y bus with ECC protected DDR2

must provide a long product lifetime and that these products must be ruggedized in order to withstand the harsh environments where these products are most often used—can be addressed by changing the way that graphic processing units (GPUs) are developed and deployed for the safety-critical market.

memories as well as analog and digital output drivers. A custom CRT Controller implemented in the Vir tex 5 drives the analog output DACs from the frame buffer in the external DDR2 memories.

Digital outputs are driven from the same frame buffer using the highspeed SERDES available on the Vir tex 5. The video controller is fully programmable providing not only video format timings but also NTSC and STANAG voltage levels.

Sentiris AV1, in addition to its safety-critical DO-178B and DO-254 certifiability, meets the shock, vibration, temperature and other requirements of MIL-STD-810F, making it well suited for the harsh and demanding environmental conditions posed by military and civilian field-computing implementations.

But the needs of the safety-critical market are long product lifetimes and ruggedness. A real-time video processing system in a commercial aircraft, flightcertified helicopter radar, or a real-time map system (Figure 2) are all required to be designed for deployment for a decade or longer. With GPUs becoming obsolete

This map/location display is one application that is of major value to the embedded, safety-critical market.

Figure 1 illustrates one such application for the safety-critical market that is insufficiently met by today’s deployable systems. The need, then, is for an obsolescence-proof GPU, one that makes use of an FPGA-based video and graphics processing core instead of the traditional approach of using dedicated GPU ASICs. The very nature of the 3D graphics industry is in opposition to the needs of the safety-critical market. Historically, the next-generation 3D graphics ASIC is usually only 6-12 months away. What this enables for the gaming market—frequent improvements in performance—is counter to safety-critical applications.

GPUs have typically had a lifecycle of a matter of years before becoming obsolete. When the application is a gaming console, a new GPU can mean the release of a new product.

in a matter of years, engineers in this market have been faced with a dilemma: to either forgo the benefits of 3D in a safetycritical application, or to develop a workaround that enables them to obtain a hardware waiver based on a statistical time test. They then must purchase enough material upfront to ensure availability over the projected lifetime of the product. This process, however, is a workaround that, while technically in compliance with the letter of DO-178B, fails to independently certify actual compliance. Thus, products that leverage GPUs with this waiver are fundamentally unproven—with people effectively looking the other way for lack of a better solution. The 3D graphic ASIC development cycle is not going to change, so the safety-critical market needs to resolve its obsolescence and certification issues by leveraging existing technologies in new ways.

SOLUTIONS Engineering

The Fully Certifiable, Obsolescence-Proof XMC GPU

Instead of trying to obtain DO-178B and DO-254 waivers for an older generation of commercial GPUs, the goal is to develop a GPU that specifically meets the requirements of the safety-critical market. This new GPU would be easily certifiable to DO-178B and DO-254, avoid having to customize XMC Mezzanine Cards based on commercial GPU reference designs, avoid rewriting commercial drivers, and be developed specifically to address the environmental issues facing safety-critical deployments.

By eschewing the traditional approach to a GPU, we can design a GPU from the ground up—with the needs of the safetycritical market in mind.

Objective number one is to pursue a rapid development process to get to market as quickly as possible. If we leverage an FPGA with an internal PowerPC core as the primary development platform, the FPGA will allow for rapid prototyping of the GPU blocks, with the ability to move to an ASIC after development is complete. The PowerPC core’s ability to run a full Linux kernel will allow for an easy and familiar development and debugging environment, thus helping to accelerate the development process.

When moving to full DO-178B certification, Linux is easily removed and replaced with a simple executive that runs the same code developed under the Linux kernel.

Objective number two is to select hardware and software platforms that are geared toward the needs of the safety-critical market. This was a primary consideration at Quantum3D during the development of Sentiris AV1, our newest XMC (see sidebar “Sentiris AV1: Toward an Obsolescence-Proof GPU”).

In looking at the feature set needed for a safety-critical GPU, we realized that the determinism of the OpenGL SC API far outweighed some of the non-deterministic advanced rendering features available in OpenGL ES or OpenGL 2.x found in many of the commodity GPUs. For DO-178B certifiability, we leveraged an existing OpenGL SC software ren-

dering engine that already had artifacts leading to DO-178B certification. Then, we built up the hardware on a DO-254 XMC Mezzanine Card with the ruggedness needed for harsh safety-critical and military embedded environments. This approach allows for an entirely new type of GPU to be crafted—one that is based on a known DO-178B software renderer with a ground-up hardware design that

meets the rigors of the safety-critical market.

Within the safety-critical and military embedded environment, there is no de facto standard for operating system or hardware platform. Understanding that the market is fractured and wanting to address as much of it as we can, the next goal is to design the system in such a way as to make it easy to port to

new systems. Moving much of the complexity of a typical device driver from the host into the PowerPC core makes it possible to deliver a small, lightweight and portable device driver. This ensures operating system independence, thus enabling the capability to easily port to and support the various real-time operating systems that are required in the safety-critical and military embedded markets.

Typical operations, such as register setup for various operating states, are fully implemented in the on-chip PowerPC processor. This shifts the common paradigm of communication between the host and XMC from a register-centric view to a command-centric view where the host driver issues a command and the PowerPC executes the command with the knowledge of the appropriate registers to set. This means that, since the registers do not need to be mapped through the host hardware or exported to the host device driver, porting to new systems is radically simplified and provides for the wide range of hardware and operating systems common in this marketplace.

Finally, it is important to consider the easiest path to DO-178B software certification. For Sentiris AV1, Quantum3D leverages an OpenGL SC rendering engine that is based on our company’s IGL 178DO-178B certifiable renderer. This approach gives the flexibility to start with a pure software renderer and move the rendering pipeline into hardware as the project develops. The OpenGL SC engine takes the same philosophy as the rest of the system, with the host driver being as simple as possible. The host driver is only responsible for tokenizing the OpenGL SC commands and sending those commands as payload packets to the core OpenGL SC engine in the XMC hardware.

A New Set of Applications

Engineering an obsolescenceproof GPU for the safety-critical market requires a revolutionary approach.

To meet the long-life and ruggedness requirements of this market, it is nec-

essary to buck the trends that have defined GPU development to this point in time.

The benefits of such an approach are equally revolutionary. Because it is the code that is being certified—and because such code can be updated or put on subsequent generations of FPGAs without losing its certification—the safety-critical market will for the first time have a GPU that is legitimately certified, does not obsolete with EOL’d products, and is designed to meet the rugged requirements of the military/embedded applications for which safetycritical is so common.

The physical interface for SUMIT is provided by one or two highspeed, high-density Samtec QFS/QMS connectors with a 0.635 mm pin pitch. Use of this connector pre-qualifies SUMIT for Generation 2 PCI Express and USB 3.0 data rates of 5 GTran/s.

Pico ITXe

Again, unlike earlier specifications of this nature, SUMIT does not specify a board form factor. Indeed, the SUMIT I/O expansion interface may be built onto any of a wide range of industry standard board form factors, such as EPIC, EBX, PC/104, Mini-ITX and more. The small PCB space requirements of the SUMIT interface are combined with a desire to take advantage of the super high level of integration found among next-generation, ultra-low-power processor / chip set combinations such as Intel’s Atom and VIA’s Nano. As a result, the SFF-SIG is offering a new, ultra-small SBC form factor standard called Pico-ITXe. This tiny 72 x 100 mm board enables a new class of compact footprint embedded applications with

stackable I/O expansion. Optimizing for ultra-low-power platforms leads to a short stack height of only 15.24 mm.

In another major break from the past, the Pico-ITXe specification does not specify a fixed location for the SUMIT expansion connectors. Since the location of the I/O module on such a small board has limited impact on overall system design, and since the routing of many hundreds of high-speed traces on a small PCB represents an enormous design challenge, flexibility in the module location makes the SBC much easier to design. The only requirement is that the I/O module not overhang the edge of the Pico-ITXe board and the relationship between the SUMIT connectors and expansion module mounting holes be maintained.

The Pico-ITXe Specification will show several examples of module placement (Figure 2), any of which constitutes an implementation that is compliant with the standard. In addition, the SFF-SIG will provide examples showing potential I/O module placement, using the SUMIT interface, on other industry standard form factor boards including EPIC and PC/104.

Such a small SBC form factor as Pico-ITXe mandates the definition of an ultra-small I/O expansion module.

For use on Pico-ITXe SBCs (as well as any larger SUMIT-compliant SBC), the SFF-SIG has defined a new I/O module standard called Pico I/O. These stackable 60 x 72 mm boards can grab any of the bus interfaces available on the SUMIT interface while passing the remaining interfaces to the module above. Hence, Pico I/O could embrace a x1 or x4 PCI Express interface, LPC interface, USB interface, I2C, or SPI, or a combination of these. Both the PicoITXe and Pico I/O Specifications are slated for release to the public at the end of 2008. Draft versions are available now to SFF-SIG members.

MiniBlade device and its latching socket.

providing all the tools for a small, nextgeneration embedded system design.

However, they alone are not sufficient.

Embedded systems need additional elements to be complete. One of those key elements is mass storage. The SFF-SIG is addressing the need for small, rugged mass storage for embedded systems via the MiniBlade Specification. Adapted from the SiliconDrive II Blade Specification originally created by Silicon Systems and Samtec, the MiniBlade Specification defines a connector, pin definition and module form factor for small, rugged removable subsystems such as mass storage and other I/O technologies. Unlike consumer-grade dongles and thumb drives, MiniBlade specifies a latching socket mechanism for increased resistance to shock and vibration (Figure 3).

Like commercial standards, the pin interface for MiniBlade is sufficiently flexible to enable I/O modules such as wireless interfaces, GPS and other I/O technologies. The creation of the final MiniBlade Specification is currently underway. Members of the SFF-SIG are invited to join the MiniBlade Working Group (MWG). The MiniBlade Specification should be published in the first quarter of 2009.

Early drafts will be available to SIG members.

The last key specification to be included in this initial set from SFF-SIG addresses perhaps the most dominant trend within the embedded board space—Computer-on-Module products. There have been multiple attempts to create industry standards for COM modules that incorporate next-generation bus technologies. The bulk of these, however, are beset by issues that affect carrier board design ranging from a lack of interoperability among modules implementing the same standard to the need for custom BIOS development to support carrier board I/O. While dozens of embedded OEMs have brute-forced their way through these issues, SFF-SIG believes that the time has come for a next-generation COM standard that learns from these mistakes and eliminates these issues through the inclusion of an appropriate mix of legacy and leadingedge signals. This new specification, designated Computer-On-Module Interconnect Technology (COMIT), is still in its formative stage with the COM Working Group at SFF-SIG. The concept, as initially outlined in the October 2008 issue of RTC, is to bring back to the module those devices which made implementation of earlier standards such a headache.

These include: • Two traditional serial ports to eliminate many if not all custom BIOS requirements • The LPC bus to enable easy support of legacy (ISA) devices on the carrier board • Ability of the module to operate on system power, generating all necessary voltages on the module • Providing all necessary power planes and control signals to ensure a full ACPI implementation Like the SUMIT specification described earlier, the COMIT Specification describes a connector and pin definition for Atom and Nano platforms, leaving the module form factor open. The COMIT interface can be implemented on any of the existing COM form factor standards such as ETX / XTX or any of the multitude of COM Express form factors. The single 240-pin COMIT connector (Fig-

COMIT signals include: • 3 PCI Express x1 lanes • 1 PCI Express x4 lane • 6 USB ports • VGA + PnP • Dual LVDS panel support (24-bit) • SDVO (Serial Digital Video Out) • 2 SATA channels • HD AC’97 audio • LPC Bus • 8-bit SDIO • 2 Serial UART ports • SPI/uWire • SMBus / I2C • Power, Ground and various control signals Manufacturers and system OEMs interested in participating in finalizing the definition of the COMIT Specification should contact the SIG. The first publication of the COMIT Specification is expected in the first quarter of 2009. A draft version will be available to SIG members late in 2008.

This ambitious plan—the release of four significant new industry standard specifications in its first year of existence—provides a resounding basis for continued growth of the SFF-SIG. For as systems shrink in size, and technol-

ogy evolves to meet the needs of small form factor systems, additional areas need to be addressed. In addition to the requirements imposed by new processor / chipset solutions as well as new expansion bus architectures, the small form factor community would benefit from standards in the area of power supplies, cooling solutions, external graphics adapters, ruggedized RAM modules and many more.

A small number of dedicated individuals have driven the SIG to this point in time. Growth to the next level will require more effort from subject-matter experts. The SIG provides an excellent vehicle for suppliers to gather with their competitors and customers to define longlived standards that will grow the market opportunity for everyone. Our industry, and the standards that drive it, are only as good as the standardization efforts made by the industry’s technology leaders. The SIG welcomes your membership, but more importantly, the contribution of your time, talent and resources to build sustainable, long-lived standards for the benefit of all.

Secure Software and Systems: Follow Five Principles and Prove It To be truly secure, computer systems, their operating systems and software must meet stringent criteria—criteria not determined by the market but by expert testing up to and including the National Security Administration.

by D avid Kleidermacher Green Hills Software

T

he world has become accustomed to the fail-first, patchlater mentality of insecure software and computing infrastructure. As Michael Vatis, a former director of the FBI’s National Infrastructure Protection Center, has said: “The vulnerabilities are endemic because we have whole networks and infrastructures built on software that’s insecure. Any given day, some new vulnerability pops up.” Thus, much of the world’s critical infrastructure, financial networks, medical information systems, telecommunications gear and portable mobile devices are open to compromise by determined individuals, corporations, organized crime and nation states.

While the world spends untold billions on snake-oil solutions— firewalls, filters and Patch Tuesdays—security experts know full well that the only true path to security is through high assurance.

Users of high assurance software can have high confidence in the ability of that software to securely perform its intended function.

Almost all of the world’s commercial software is low assurance, and our confidence level in its security matches. Yet recent developments have proven that high assurance software can be practical, even for complex applications such as operating systems.

Green Hills has developed and applied an architecture—the Secure Separation Architecture—to create a wide variety of highly secure components, applications and complete systems. Such an architecture should help computer and security professionals as well as the average consumer understand what is meant by high assurance. The architecture prescribes a set of five principles to be

36

December 2008

used in the creation of secure software and systems. Some of these may be familiar, while others may not be obvious; all are critical: 1. Minimal Implementation It is much harder to create simple, elegant solutions to problems than complex, convoluted ones. Most software developers do not work in an environment in which producing the absolute minimal possible solution to a problem is an unwavering requirement. Spaghetti code is the source of vulnerabilities that run rampant in software and provide the avenue of exploitation for hackers.

2. Componentization Compose large software systems from small components, each of which is easily maintained by (ideally) a single engineer who understands every single line of code. Use well-defined, documented interfaces between components. An important corollary to this rule is that security-enforcing functionality should be placed into separate components, so that security functionality is protected from compromise by unrelated functionality. Componentization provides many benefits, including improved testability, auditability, data isolation and damage limitation. Componentization can prevent a failure in one component from devolving into a system failure.

3. Least Privilege Components must be given access to only those resources (e.g. communication pathways, I/O devices, system services, information) that are required. Access control must be mandatory

for critical system resources and information. This is a biggy.

In most operating systems, it is the birthright of any program to access the file system, launch other programs, and manipulate system devices. This lack of least privilege design enables a simple vulnerability, such as a buffer overflow, to be exploited to maximum deleterious effect.

4. Secure Development Process For the critical security-enforcing components, the software development process must meet the highest levels of reliability assurance, such as DO-178B Level A (a standard for ensuring the safety of flight-critical systems in commercial aircraft) or equivalent—as well as the highest levels of security assurance—EAL 6/7 or equivalent. This assurance process will cover numerous controls, including configuration management, coding standards, testing, formal design, formal proof of security policy, etc.

5. Independent Expert Validation Intrinsic assurance evidence must be evaluated and confirmed by independent experts. Consumers who read about a vendor’s claim of “certifiable” should interpret such hyperbole as “not certified.” For example, to achieve certification to the high assurance Separation Kernel Protection Profile (SKPP) in the United States, a separation kernel must not only have all of its design documentation, testing and formal methods painstakingly evaluated by an accredited Common Criteria testing lab, but the product must also undergo penetration testing by the NSA’s penetration testing experts who have complete access to the source code and essentially unlimited resources with which to craft attack vectors.

Software that fulfills all five principles (it’s easy to see how the lack of any one of them can be fatal) can be trusted to manage and protect high-value assets, even if those assets are under attack by the most determined and resourceful enemies (read “exposed to the Internet”). The Secure Separation Architecture

does not attempt to rigorously define “secure development process” or specifically how the principles of least privilege apply to a particular software component or system. Interpretations will necessarily vary depending on the situation.

Common Criteria

Common Criteria is an important part of the answer to this interpretation dilemma. Common Criteria—more formally known as ISO/IEC 15408—is the international standard for evaluating the security of IT systems. Under Common Criteria, IT products are evaluated against Protection Profiles, which specify the product family’s security functional requirements and security level called the Evaluated Assurance Level, or EAL. For example, there are protection profiles for firewalls, antivirus applications and operating systems.

Protection profiles themselves must be evaluated, ensuring that products are measured against a well-understood, valid and accepted standard. There are five operating system-related protection profiles that have been evaluated by the U.S. Government (http://www.niap-ccevs.org/cc-scheme/pp/). These operating system specifications have varying security levels, making them more or less appropriate for certain threat environments. The operating system profiles and their applicable threat environments are listed in Table 1.

As can be seen from Table 1, only the SKPP is appropriate to protect high-value information exposed to the threat of sophisticated and determined attackers. In agreement with the secure development process principle, according to Common Criteria, EAL 4 “is the highest level at which it is likely to be economically feasible to retrofit an existing product line.” There is more to security than using the word “secure” or “trusted” in product names and press releases.

Defense Against the Dark Arts

In 2007, IEEE Spectrum published The Athens Affair (http:// www.spectrum.ieee.org/jul07/5280), detailing the recent incident in which the Greek Prime Minister and a slew of other high ranking dignitaries had their mobile devices bugged. Hackers infiltrated the cellular provider’s computer systems to inject software that maliciously redirected private communications. Investigators concluded that the computers were “reprogrammed with a finesse and sophistication rarely seen before or since.” The Athens Affair was a well-funded and determined breach of system security by hostile entities.

The number of detected intrusions into U.S. government networks has been steadily on the rise. For example, the Department of Homeland Security suffered 850 known cyber attacks in a two-year period beginning in 2005. Security experts believe that the actual number of successful breaches is far higher. The truth is that we have no idea what has already been stolen or commandeered, awaiting the opportune moment to strike. Too many IT professionals believe that encrypted communications, Web filters, firewalls and other security appliances are sufficient to protect valuable assets. Talk to one of the leading ethical hacking firms (better yet, hire them to attempt to infiltrate your corporate network), and you will soon be convinced that these technologies are akin to putting a padlock on a screen door. Ironically, the security appliances themselves run insecure operating systems.

Many of the security problems that plague IT infrastructure can be cured with a Secure Separation Architecture and its use of

high assurance certified products, such as SKPP-certified operating systems. The requirements of the SKPP are far more stringent than any other operating system security standard. The resulting assurance, or confidence, that developers, users and other stakeholders are therefore able to derive from this certification is extremely high and unprecedented in the world of computer security. The Secure Separation Architecture is now being applied to solve important security problems in corporate, civil and government computing infrastructure.

Atom-Based Qseven Module Addresses the Portable Device Market The first computer module based on the new Qseven form factor was specially developed with an eye on the latest lowpower processor technology and demand for small physical size.

With a typical power consumption of <5 watts, mechanical dimensions that are scarcely bigger than a credit card, integrated battery management and ACPI 3.0 power management functions, the conga-QA from congatec is specifically suited for all mobile applications. The conga-QA is fitted with the latest Intel Atom Z5xx range of processors and the Intel US15W system controller hub.

The new module provides fast, serial differential interfaces such as PCI Express and SATA, although it consistently avoids old “legacy“ interfaces such as EIDE and PCI to ensure that future generations of CPUs and chipsets can also be used without problems. It provides 8x USB 2.0, 1x SATA, 1x SDIO, 1x PCIe, LPC bus, I²C bus as well as gigabit Ethernet and high-definition audio. The new module further offers up to 4 Gbyte onboard flash storage as an option for robust mass storage. The flexible SDIO interface means that SD cards can also be used as easy and robust mass storage. Thanks to the 8-bit bandwidth, MMC 4.0 cards can be used with a data transfer rate of up to 52 Mbytes/s. In addition to storage media, cards with functions such as WLAN, Bluetooth, RFID, etc. are also available for the SDIO standard.

The conga-QA is available in two CPU variants. The lowercost version is based on the Intel Atom Z510 processor with 1.1 GHz core frequency and 400 MHz front-side and memory bus.

In contrast, the high-end version contains a 1.6 GHz Intel Atom Z530 with 533 MHz front-side and memory bus. Both versions have a 512k L2 cache and can access 512 Mbytes of onboard DDR2 storage.

The Intel US15W system controller hub contains the Intel GMA500 graphics engine. The 3D-capable onboard graphics use a frame buffer of up to 256 Mbytes and support DirectX 9.0E

and OpenGL 2.0. Video applications are accelerated by MPEG2 and MPEG4 decoding in hardware. Graphics output is either via a 1x24-bit LVDS channel or an SDVO port. The conga-QA module uses VESA standard “DisplayID” to automatically recognize any flat displays connected.

All congatec boards are equipped with the congatec embedded BIOS. They also contain a board controller, which implements some of the embedded BIOS expansions. The independence from the x86 processor means functions such as system monitoring or the I²C bus are faster and more reliable, even when the system is in standby mode.

Qseven is the first embedded module definition that defines a unique software API, which covers functions important to many professional applications such as watchdog timer, I²C bus, LCD brightness control, BIOS user storage areas or monitoring system temperatures. Qseven modules from different manufacturers can therefore be exchanged flexibly without any hardware or software modifications. The congaQA will be available from April 2009. The unit price with the Intel Atom Z510 is likely to be around € 125. congatec Cardiff-by-the-Sea, CA. (760) 635-2600. [www.congatec.us].

Module Provides Digital I/O Expansion for Pico-ITXe SBCs

A new Pico-I/O module is designed for expansion on Pico-ITXe SBCs. The PCOUIO48-G from WinSystems is a 48-point digital I/O interface with interruptible event sense. An important feature of the card is that it can monitor 24 of the rising and falling digital edge transitions, latch them and then signal the host processor that a change of input status has occurred. This is the most efficient way of sensing and signaling a CPU of real-time events without the burden of continuous polling of the digital I/O points. Pico-I/O modules are designed to offer low-cost I/O expansion for Pico-ITXe single board computers from VIA and other manufacturers.

The PCO-UIO48-G’s I/O controller is based upon a Lattice FPGA programmed to support various input/output and interrupt configurations. Each I/O line is programmable for input, output, or output with read-back operation. Each line’s transition is latched so that even short duration pulses will be recognized.

The module requires only +3.3 volts; however, an optional onboard regulator is available to allow it to be powered from +5VDC. Operational temperature range is from -40° to +85°C. A Pico-I/O module is small and measures only 60 mm x 72 mm, which is half the area of a PC/104 module. Pico-I/O is based upon the Stackable Unified Module Interconnect Technology (SUMIT) connector that was developed and standardized by the Small Form Factor Special Interest Group last year.

SUMIT is an electromechanical connectorization specification that enables stacking of common serial and legacy chipset expansion buses on I/O modules for next-generation embedded systems products. Single unit pricing starts at $59.

Products & TECHNOLOGY COM Express Module with Graphics, Power Management and CPU Options

A new COM Express CPU harnesses the high-speed AMD Turion CPU with integrated ATI graphic engine and chipset to balance high performance and power consumption. The SOM-5781 from Advantech also works smart to maintain the reliability of applications through a “Smart & Secure” utility feature.

The SOM-5781 has an onboard chip that will dynamically adjust the fan speed to regulate the CPU temperature. Because the CPU fan runs at high speed only when the system is under high loading, power consumption and noise created by the fan can be drastically reduced. Using Advantech’s “SUSI” API tool, a “reduce CPU speed” command can be immediately executed to prevent a system crash when SOM-5781 detects an abnormal status from the CPU fan.

At the same time, an alarm message can also be issued to the system administrator via Ethernet.

SOM-5781 uses the AMD M690E integrated chipset with high-performance ATI graphic engine, and an additional external 128 Mbyte graphic memory (Side Port) can be added on SOM-5781 for an extra 20% graphic performance boost. SOM-5781 also supports 48 / 24-bit LVDS TFT LCD panels, DVI and PCIe x8 for external graphic cards, and it provides several different kinds of multidisplay configuration options for customer applications. With AMD S1 CPU socket on board, SOM5781 provides flexible CPU support options for customers. From extreme low power consumption Sempron 2100+ 1 GHz at 8 watts, to Turion 64 TL-62 at 2.1 GHz with dual core engine.

SOM-5781 also comes with I/O capabilities that include: four PCIe x1 and one PCIe x 8 or 1 x DVI interface, 1 x GbE LAN, 4 x SATA, 1 x EIDE, 8 x USB 2.0 ports and High Definition audio. Advantech COM (Computer on Module) series is backwardly compatible with existing hardware and software systems. They are fully scalable for upgrades or changing application needs and feature long life support so important to embedded developers. Advantech’s own SUSI (Secure and Unified Smart Interface) API library speeds software development, and global logistics and support streamline the product development process.

STD Bus x86-Based SBC Targets Legacy Applications

A high-integration STD Bus single board computer (SBC) based on Advanced Micro Device’s (AMD) LX800 CPU is targeted to provide both an upward performance migration path and a continued source of supply for STD Bus SBCs while maintaining hardware, software and I/O compatibility. The STD Bus was first introduced in 1978 and is still in use by key industrial customers. The LPM-LX800 from WinSystems supports Windows XP embedded, Linux and other x86 real-time operating systems while offering continuing longterm availability.

The LPMLX800 incorporates the low-power AMD Geode LX800MHz 0.9W CPU that offers product availability through at least 2015. The LPM-LX800-G can be populated with up to 1 Gbyte of system DRAM and up to 16 Gbytes of CompactFlash. A high-performance video engine is on board that supports LCD and CRT displays simultaneously. Also, an Intel 82551ER, 32-bit PCI 10/100 Ethernet controller supports networking.

Further I/O support includes four USB 2.0 ports with in-rush and over-current protection, four independent RS-232/422/485 full-duplex serial UARTs, 48-lines of TTLcompatible digital I/O and AC97 audio. The LPM-LX800 contains the core logic to provide PC-compatibility for the I/O and bus interface logic including the UDMA100 controller for hard disks, keyboard/mouse controller, LPT interface, real-time clock and interrupt controller. A precision power-fail reset circuit, activity LED, PC/104-Plus expansion and watchdog-timer are also included. All of these features are included on the 4.5” x 7.0” STD Bus board.

The LPM-LX800 can functionally replace other Pentium-based STD Bus SBCs from Ziatech, Versalogic and Micro/sys; and offers long-term availability with a lower cost.

WinSystems offers free application engineering assistance. Single unit pricing for the LPM-LX800-G starts at $895.

Small 48-Point Digital I/O Module Uses SUMIT Standard

Earlier this year, the Small Form Factor Special Interest Group introduced the SUMIT (Stackable Unified Module Interconnect Technology) connector standard. SUMIT is an electromechanical connectorization specification that enables stacking of common serial and legacy chipset expansion buses on I/O modules for next-generation embedded systems products. Some of the first products supporting that standard have started to emerge. WinSystems, for its part, introduced the first Pico-I/O module designed for expansion on Pico-ITXe SBCs. The PCO-UIO48-G is a 48-point digital I/O interface with interruptible event sense.

An important feature of the card is that it can monitor 24 of the rising and falling digital edge transitions, latch them, and then signal the host processor that a change of input status has occurred. This is the most efficient way of sensing and signaling a CPU of real-time events without the burden of continuous polling of the digital I/O points. Pico-I/O modules are designed to offer low-cost I/O expansion for Pico-ITXe single board computers from VIA and other manufacturers. The module requires only +3.3 volts; however, an optional onboard regulator is available to allow it to be powered from +5 VDC. Operational temperature range is from -40° to +85°C. A Pico-I/O module is small and measures only 60 mm x 72 mm, which is half the area of a PC/104 module. The PCO-UIO48-G lists for $59. A depopulated version with 24 lines, called the PCO-UIO24-G, lists for $49.

PXI Card Blends Boundary Scan and Dynamic Functional Test

System developers can now get more bang for their buck when it comes to test instrumentation gear. That’s because multi functions are now available on boards that used to require several. Goepel Electronic has launched a new series of JTAG Digital I/O PXI modules named PXI 5396-x. The PXI 5396-x modules offer 96 individually configurable single-ended channels and support the structural JTAG/Boundary Scan test as well as dynamic I/O operation up to 100 MHz to execute functional tests.

PXI 5396-x are 1-slot 3U modules, which differ in onboard memory depth of 72 Mbytes (PXI 5396-X) and 144 Mbytes (PXI 5396-XM). All modules offer 96 single-ended channels configurable as input, output and tri-state, which allow simultaneous driving, measuring and real-time comparison. While the signals are processed to test bus operations completely synchronous in the JTAG mode, the dynamic I/O mode enables functional testing with freely programmable clock frequencies from 500 Hz to maximum 100 MHz. That’s why first structural Boundary Scan tests and afterward functional tests can be executed with the same instrument.

FPGA-Based I/O Module Family Rides PXI

There’s always been conflict between the need for applicationspecific flexibility and standards-based I/O instrumentation. National Instruments tackles that head on with a new family of open, FPGAbased hardware for the PXI platform. With NI FlexRIO, engineers can add custom signal processing algorithms to their PXI-based field-programmable gate array (FPGA) hardware.

Then, with interchangeable adapter modules, they can directly interface the FPGA to instrument-class I/O or create their own custom front-end hardware to meet their specific application requirements.

NI FlexRIO FPGA modules feature high-performance Xilinx Virtex-5 FPGAs. Using LabVIEW FPGA, engineers gain direct access to raw digital pins on the NI FlexRIO FPGA modules, with 66 differential lines at up to 1 Gbit/s per pair or 132 single-ended lines at up to 400 Mbits/s. In addition, NI FlexRIO FPGA modules offer deep onboard memory and the ability to use external clocks. All NI FlexRIO implementations require two distinct hardware pieces—a PXI FPGA module and an adapter module, which defines the specific I/O capabilities of the system. The first NI FlexRIO adapter module is the NI 6581 high-speed digital I/O adapter, which is ideal for algorithmic pattern generation and protocol-aware tests. Pricing for the modules ranges from $999 to $4,999 depending on configuration and type.

Winding Down or Winding Up?

A

s we look back on 2008 and forward to 2009, it’s a real tough call as to which way things are going. This year (2008) certainly ended on a sour note as the financial markets continued their downward spiral despite bailout efforts and some $700 billion in the Troubled Asset Relief Program (TARP).

The technology industry in general took a nosedive as judged by the technology-rich NASDAQ index, which dropped some 50% in October and according to some in the financial industry may drop another 50% in the coming 18 months. For example, Intel Corp lost 50% of its value since the end of October and other technology companies shed similar amounts.

Translation to Embedded Computer Biz

The embedded-computer business hasn’t necessarily followed the technology shares, but it does have some relationship.

Looking at previous dips and bumps in the industry, the embedded-computer business tends to lag the general technology business by some six to nine months. If that’s the case, we may be facing a bleak new year.

Other evidence that things are slowing comes from the durable goods numbers, which fell by more than 6% last month. Business equipment spending, the heart of the business for non-defense spending on embedded computers, dropped 4% in October after more than a 3% drop in September. The good news is that spending is up year-over-year, but the trend is definitely in the wrong direction. Blame this on tight credit, or a sagging consumer market or whatever, it still doesn’t spell good news. Pipelines that were being filled since the end of the summer have not been depleted and the flow of finished products has slowed dramatically.

And it gets worse. ChangeWave Research, which has studied tech spending plans of thousands of businesses since 2001, found that 45% say they will decrease tech spending or drop it completely in the next quarter. Some 39% say they have spent less this quarter, and 48% say they don’t think tech spending will pick up again until after the third quarter of 2009.

On the Down Side

Several related tech companies are reporting problems for the upcoming period. Intel, for example, slashed its sales outlook showing a 12% decline from the third quarter. However, not all news on the Intel front is bad news. Earlier this month the company rolled out its Core i7 chip, the first member of its highly anticipated processor family. The chip, code-named Nehalem, is targeted at high-end desktop computers.

Chip equipment maker, Applied Materials, also gave a dire forecast saying revenue would drop 14% in the fourth quarter.

The company is cutting some 1800 jobs or 12% of its workforce.

It looks like the move to larger wafers will have to wait another six to twelve months. The semi-equipment maker sector is a strong buyer of embedded computers and electronics.

On the finished-goods end, Nokia—the world’s largest mobilehandset maker—drastically cut its outlook for the fourth quarter.

Other cell phone makers are also bracing for the shakeup. Qualcomm projects a major contraction in its sales of cell phone chips, and Vodafone warned of a shortfall in its earnings. Analysts are predicting declines of as much as 9% in cell phone sales next year.

Can a dip in the cell phone infrastructure be far behind?

And on the supply end, Longbow Research reports that con-

nector companies missed forecasts showing a decline in the low to mid-single digits. Once again, citing the burst of the dot-com bubble, connector companies are in a lot better shape. In 2001, companies double and triple ordered components to make sure they could satisfy current needs. When the bubble burst, sales went to zero (and in many cases below zero as companies began returning merchandise).

And, unfortunately, layoffs are rampant. Sun had a major layoff recently, slashing some 5000 to 6000 jobs. Nortel let go some 1300, and overall, it’s been reported that through the end of October, computer, electronics and telecom industries have cut more than 140,000 jobs. Two-thirds of these have taken place since July, showing a trend being in the wrong direction.

A Bright Spot?

While a good part of the market may be looking flat, supercomputers may be the only bright spot. New chip technology, including the use of multicore chips initially designed for graphics such as the 240-processor chip from Nvidia, will bring supercomputing to the desk with systems selling for less than $10,000. Another entry from Super Micro Computer boasts 20, four-processor chips and sells for $30,000.

Sales of the largest machines—above $500,000—grew 16% in 2007 to $2.9 billion. Smaller systems priced from $100,000 to $250,000 gained a whopping 26% to well over $4 billion. Research firm IDC projects the industry will enjoy annual growth in the area of 9% for the next five years in all price ranges.

A list of the big supercomputer winners in terms of performance, at least according to researchers at the University of Mannheim, along with the University of Tennessee and the DOE National Energy Research Scientific Computing Center, was compiled and looked at the top 500 fastest computers. A supercomputer at Los Alamos National Laboratory squeaked by the closest contender from Oak Ridge National Laboratory for the top honors.

IBM accounted for 188 of the 500 systems on the list.

At the chip level, Intel topped the bill with its chips powering 379 of the top 500. AMD was next with 59 machines including seven of the ten fastest. The number one machine (Roadrunner) used both AMD and IBM processors, while the runner-up used only AMD’s Opteron chips. The new breed of graphics chips have yet to break into the top ranks.

Patent Trolls

Periodically in these pages we talk about patent trolls and how they impact our industry. In the past, we’ve had some of these patent-troll companies assert patents against some members of the embedded computer community. For the most part these have been largely nuisance attacks; however, some have caused vendors to trot out the legal beagles. Patent trolls are those companies that generally buy up patents en masse and take a scatter-gun approach to assert them against anyone they can—usually going after larger companies with big budgets that will pay off nuisance suits rather than be bothered to defend against the assertions.

The politically correct term for the trolls is “non-practicing

entities” because they don’t make or sell products using the patents. The patent trolls rose to prominence when one of them successfully asserted a patent against Blackberry maker RIM and won a sizeable settlement—enough to jeopardize the financial health of the company.

Most recently, a San Francisco start-up is offering a new service to address patent risks facing technology companies. The new firm, RPX Corp., wants to become what it calls a “defensive patent aggregator,” buying patents to keep them from patent-troll companies. It’s similar to the Allied Security Trust formed by a handful of large technology firms in June (see NV&C July), but RPX plans to make a profit from membership fees ranging from $35,000 to $4.9 million. Uhh, is there something I’m missing here? If you can’t beat them, join them?

One of the leaders of the patent troll business is Nathan Myhrvoid. Over the past few years, the former Microsoft executive has amassed some 20,000-plus patents and applications and is pushing tech giants to sign some of the most costly patentlicensing deals ever negotiated. His firm, Intellectual Ventures, has received some $200 to $400 million in recent months from companies including Cisco, Verizon and others. He is not high on their popularity parade.

The solution? I’m not so sure there is any on the horizon.

In a system where companies such as Intellectual Ventures can flood patent examiners with hundreds of patents annually—most of which will be granted—then shake down businesses to avoid lawsuits, there isn’t much hope. It appears that a makeover of the U.S. patent system is going to be needed. Once the new administration takes care of the war on terror and the economy, it might want to look at the patent situation.

Seven-Year Boom

The worldwide chip industry is expected to see an end to the seven-year winning streak it’s been enjoying. The SIA (Semiconductor Industry Association) predicts that chip sales will drop by as much as 5.6% in 2009. While sales continued to grow for the first three quarters of 2008 (see NV&C September), the SIA projects a 5.9% drop in the fourth quarter, which is traditionally one of the stronger periods.

The forecast is apparently echoed by market-research firm, iSuppli. Are we back to the fall of 2001? Apparently not, say researchers. In the collapse of the bubble of 2001, companies were saddled with huge inventories resulting in a total meltdown. This time around, companies have been more cautious with their ordering. The result is that while 2009 will be a down year, sales are predicted to rebound in 2010 and 2011 by 7.4% and 7.5% respectively.
