lnvestment Casting:

“Digital Foundry”

Technology Dramatically Reduces Cost, Lead Time

In modern aircraft engines and industrial gas turbines (IGT), investment cast parts are made of expensive superalloys to withstand the extreme thermal, mechanical, and chemical loads experienced by these hot gas path components. For decades, these high value parts have been made through a labor-intensive, multi-step lost-wax investment casting process. This approach requires twelve separate steps to produce finished castings. Given the time and investment, many turbine OEMs avoid design changes once a part is in production. Now, a new category of “digital foundry” technology significantly cuts lead times and costs when creating the complex parts found in jet engines and IGT turbines. The modern process delivers the convenience and speed of ceramic 3D printing to create the molds, with the precision of investment casting. The solution is ideal for turbine parts due to the feature resolution, overall build level, and ability to produce parts at production volumes. Compared to traditional investment casting, the technology can lower the cost of manufacturing parts by over 50% and decrease lead times for new or modified parts by a factor of ten. The more complex the part, the greater the reduction in cost and lead time since it is very difficult to produce complex geometries with traditional tool and die methods in the lost-wax investment casting process. The technology can produce precision investment castings of complex engineered components without any up-front investment in hard tooling and without any patterns using 3D printed ceramic shell molds. The fully automated, digital printing technology is engineered to 6

produce parts that are equivalent to those using traditional investment casting in properties, surface finish, and dimensional accuracy. Investment Casting Market Growth and Innovation The global investment casting market size was estimated at USD 20.99 billion in 2020 and expected to reach USD 31.07 billion by 2027 according to Research and Markets, a global market research provider with 450+ of the Fortune 500 Clients. As drivers of growth, the research firm cites rising demand from the aerospace and defense industry, the use of investment casting in the automotive and transportation industry to develop advanced components, and increasing application in industrial machinery. In the U.S., the National Science and Technology Council (NSTC) of the Executive Office recently released an updated list of Critical and Emerging Technologies significant to national security that includes advanced gas turbine engine technologies. The NSTC is a cabinet-level council of advisers to the President on science and technology. However, one challenge to the expected growth of the investment casting market has been the high fixed costs of traditional part design and development. “Today, the overriding goal of aircraft jet engine and IGT manufacturers is to continue to seek new ways to incrementally increase turbine efficiency. However, even large OEMs are leery of designing new parts that require an investment of millions of dollars for new tooling when a part is unproven,” says Suman Das, founder and CEO of DDM Systems,


The Digital Foundry™ from DDM Systems combines ceramic 3D printing technology with traditional casting techniquesto create high value turbine parts, while reducing both the cost and lead time to full production.

The Digital Foundry™ solution is ideal for complex turbine parts due to the feature resolution, overall build level, and ability to produce parts at production volumes.

feature resolution available in the industry for ceramic 3D printing utilizing UV-cured resins.

The company’s Digital Foundry™ can produce optimized, 3D-printed “ready to pour” ceramic shells based on more than twenty-five patents covering equipment and methods in half a dozen countries. Once the molds are created, traditional investment casting techniques are used to create parts in production quantities.

With this approach, a Digital Foundry can respond quickly to part design changes or begin casting new parts in as little as ten days. At a traditional investment casting foundry, the lead time for first parts can take up to 52 to 80 weeks for the most sophisticated, high-performance castings.

“The first step is to take a customer-supplied CAD model and use it to design, and then 3D print it to create ceramic shells with integrated cores that are ‘ready to pour.’ There is no up-front investment in hard tooling and no patterns are required. The shells are poured utilizing the usual investment casting methods with unprecedented speed and precision in production volumes,” explains Das.

By eliminating much of the cost and time, jet engine and IGT turbine manufacturers can cast a range of design variants to conduct qualification and “rainbow wheel” tests to optimize the design of blades, inlet guide vanes (IGVs), housings, shafts, and other hot gas path parts.

The process used to create the ceramic shell is called LAMP™ (Large Area Maskless Photopolymerization). The technology uses a ceramic resin that is cured with UV light to produce shell molds with integrated cores, layer-by-layer. In LAMP, the 3D “printer head” projects images in ultraviolet light onto the resin, causing it to solidify in patterns corresponding to slices of the shell. The ceramic structures that result can achieve the high level of detail expected of investment casting cores and molds. Once the ceramic shells are printed, they must go through a thermal processing step using well-established techniques for firing ceramics. DDM possesses trade secrets related to the ceramic formulation and firing. According to Das, there is significant reduction in costs since the LAMP process eliminates seven of the twelve steps typically required to produce a traditional investment casting shell. These seven steps account for 90% of all the sources of scrap and approximately one-third of the total manufacturing cost of producing an investment casting. With the 3D printing technology, the ceramic shell is made in a single step. The LAMP machine has an adjustable build platform that can be configured to 24x24x20 in. (600mm x 600mm x 500mm) for production scale. This is the largest print platform with the finest

The printed ceramic shell is compatible with all air-melt and vacuummelt foundry processes. So, OEMs that operate their own investment casting foundries can install DDM Digital Foundry to create the molds and do the casting with existing equipment. Third party foundries can do the same, with a relatively modest investment to immediately increase capacity, speed production, and reduce lead times. DDM has completed third party qualification with castings made in over half a dozen alloys poured in foundries across the U.S. These meet all the required criteria for acceptability as published by the Investment Casting Institute. Today, the digital foundry process can produce parts in hundreds of standard air-melt steel, aluminum, and vacuum-melt nickel alloys. Airmelt Alloys currently qualified include Stainless Steel 304, 316, 17-4 PH, 15-5 PH, and Austenitic Steel CF3M (wrought equivalent SS316); S7 Tool Steel; Aluminum A356 and A357; and Air-Melt Inconel 625. Vacuummelt alloys currently qualified include IN 718, IN 713LC, Rene 141, and CMSX-4. Although the conventional lost-wax investment casting process has been used for decades, foundries that take advantage of digital foundry technology will have a competitive edge in meeting the increasing demand for complex parts with minimal cost and lead time.

VAST Federal and Mercury Systems Collaborate to Build Ruggedized Ceres Platform for Military and Defense Operations at the Edge

Leveraging VAST’s Universal Storage data platform and Ceres concept, Mercury will bring advanced data capture and AI computing capabilities to military edge operations

VAST Federal, a VAST Data subsidiary providing government agencies with mission-ready data platform solutions, announced a collaboration with Mercury Systems (NASDAQ: MRCY), a leader in trusted, secure mission-critical technologies for aerospace and defense, to deliver rugged, high-performance storage solutions for edgebased data capture and AI computing. Mercury’s upcoming rugged data storage systems will be based on Ceres, VAST Data’s next-generation storage platform concept, and will be purpose-built to meet the unique size, weight, and power (SWaP) requirements in the space-constrained platforms typical in land, sea, air, space and cyberspace deployments, where every inch and every ounce matters. Mercury’s new data storage systems will improve performance and simplify serviceability at the edge by using advanced hardware technologies including NVIDIA Bluefield DPUs (data processing units), ruler-based hyper-scale flash drives, and storage-class memory. The addition of a ruggedized hardware enclosure allows VAST and its industry team members to satisfy the data flow demands of C5ISR (Command, Control, Computers, Communications, Cyber, Intelligence Surveillance, and Reconnaissance) to achieve ultimate situational awareness from Edge Environments to Ground Station to Centralized Command and Control. Universal Storage protects data throughout the entire C5ISR system so that commanders and their personnel can have reliable and secure access to the data that informs their mission. Additional details on the benefits of the rugged data solutions with Universal Storage will include: High Performance for Mission-Critical Edge Workloads. With Universal Storage as the software foundation, systems deliver the ultimate in data center-class, exabyte-scale network-attached storage (NAS) for edge workloads, empowering military and securi12

ty personnel to quickly capture and analyze data for a real-time response when faced with national security situations. The Universal Storage data platform is a PCIe Gen4 storage system that maximizes GPU utilization for inference at the edge, accelerating AI applications that run directly on field devices for faster decision making. Additionally, having data processed locally reduces the risk of data being intercepted while in transit to the cloud. Ease of Serviceability While Maintaining System Uptime. Mercury is designing the system so that everything is front serviceable–ruler SSDs, NVIDIA BlueField DPUs, and SCM drives–and can easily be accessed when deployed in a plane, helicopter, submarine, or other space-constrained environments. Universal Storage software lays the foundation for a much more resilient architecture where failures and maintenance are non-disruptive to system operation. Meets Defense Industry’s SWaP Requirements. Whether on land, at sea, in the air, or in space, the system hardware architecture will combine with VAST’s efficiency codes to meet the SWaP requirements of edge computing — packing petabytes of data into SWaP-constrained environments. The solution will also support DC power and will perform in extreme conditions, such as high altitude and humidity levels or environments with heavy vibrations. Enhanced Data Protection for Fast Backup and Restore. To safeguard confidential data against all threats, edge computing systems must have built-in mechanisms to help prevent data losses and breaches, even in the

most remote locations. Universal Storage delivers accelerated edge dataset backups with rapid recovery for mission-critical data and applications. The Indestructible Snapshots feature in VAST’s Universal Storage prevents critical backup copies and snapshots from being altered or destroyed when in a hostile environment. “Our software-based approach allows us to team with best-of-breed technology providers like Mercury to reimagine the storage footprint for a variety of workloads at the edge, including sensor processing, AI, and data analytics,” said Randy Hayes, Vice President, Public Sector of VAST Data Federal. “This collaboration strengthens VAST’s commitment to place software at the heart of modern data infrastructure, and enables actionable insights from multiple field locations that can be sent back to Centralized Command and Control for deeper analysis and long-term data preservation.” “Teaming with VAST Federal aligns well with our approach of rapidly integrating the latest-generation commercial technologies to future-proof A&D solutions and push server-class processing to the tactical edge,” said Dusty Kramer, Vice President and General Manager, Mercury Systems Edge business unit. “Mercury-VAST rugged data Universal Storage solutions combined with our ruggedized Intel® and GPU-based servers enable deployments in distributed, space-constrained locations with SWaP-enhanced efficiency while facilitating AI and data analytics compute power at the edge to ensure crew safety and provide advanced threat assessment.”

SPECIAL FEATURE

Deterministic Software Solutions for Complex Architectures Involving Software-Defined Radio (SDR) By Brandon Malatest, Chief Executive Officer, Per Vices

Introduction

Most of today’s RF communication systems demand software tools that are capable of delivering repeatable performance. Software tools that are designed to give consistent output when the same input is provided are said to be deterministic and exhibit the same behavior every time they are executed. For software defined radio (SDR) systems, determinism is required to ensure that the behavior of a radio system is predictable and consistent. Variations in environment parameters make RF communication systems exhibit non-deterministic characteristics. In this article, we will explore how complex RF communication systems can be realized by combining SDR platforms and software solutions. Next we will focus on how the architecture of field programmable gate arrays (FPGAs) yields minimal and deterministic latency. We will also discuss how utilizing common software API such as UHD helps to enhance determinism and code portability across multiple SDR systems. This article will also explore how GNU Radio can be used to implement complex SDR systems with deterministic performance. We will also discuss one software tool that allows adjustment of parameters to optimize determinism of a radio communication system. Lastly, this article will focus on a few applications that demand deterministic performance and how SDR systems are used in their implementation. 16

COTS Journal | April 2022

Deterministic performance of SDRs A typical SDR platform features a radio front-end (RFE) that handles analog signals and a digital back-end that processes digitized signals. The RFE performs transmit (Tx) and receive (Rx) functions and is designed to operate over a broad frequency range. The highest bandwidth SDR platforms offer multiple independent channels and a high instantaneous bandwidth, up to 3GHz. High end SDR systems feature an FPGA with a broad range of onboard digital signal processing capabilities including upconverting, downconverting, demodulation, decimation, interpolation, and data packetization. SDR systems use software for a wide range of digital signal processing functions including modulation, demodulation, upconverting and downconverting. These platforms also utilize software for various RFE control operations such as gain setting, sampling rate setting and tuning. SDR platforms also utilize software to interface with various networks that they communicate with. Highest throughput SDRs are capable of sending and receiving data at high speeds over high speed links. Some of the software tools that are commonly used with SDR systems include Hardware Description Languages (HDLs), Universal Hardware Driver (UHD) and GNU Radio. To start with, UHD is an open source driver used for developing custom software tools for controlling and configuring SDR solutions. Software tools that enhance determinism in SDR solutions GNU Radio is an open source toolkit for developing complex digital signal processing (DSP) in SDR systems. Hardware description language (HDL) such as VHDL or Verilog are used for developing custom, ultra-fast and deterministic DSP functions on FPGAs. FPGA designs are analyzed and synthesized using

software tools such as Intel Quartus. SDR systems utilize FPGA for packetizing data for transmission over Ethernet or any other network stack. This requires VITA Radio Transport (VRT) standard which is a protocol that defines the format for transmitting and receiving digitized signals between radio systems. On the application programming interface (API) side, UHD is used to allow development of deterministic software and transmit/receive commands. Deterministic software tools, waveforms and commands can be ported from one SDR device to another without variations in performance. Deterministic waveforms and pulses can be transmitted at predictable time intervals and for specific durations. Deterministic performance also allows execution of various commands such as center frequency, sampling rate, filtering method, broadcasting channels, type of broadcast waveform, and so on. Determinism also aids in controlling parameters in transmit and receive functions such as the number of samples sent to the buffer and the size of the buffer. How FPGAs enhance determinism in SDR solutions FPGAs, unlike CPUs and ASICs, have highly parallel computing architectures that ensure low and deterministic latency. They are capable of performing a wide range of DSP operations on digitized signals. In most RF systems, applications running on host processors offload compute-intensive tasks to FPGAs for faster computation. The computation and storage requirements of a signal processing task increase with an increase in the sampling rate. With an SDR system, captured data can be manipulated


through decimation and interpolation techniques thereby helping to create more space on a storage device while preserving fidelity. Assessing and configuring RF systems using software GNU Radio offers a broad array of tools for controlling and visualizing the signal performance of an RF system. With this software suite, you can visualize the signal in various ways to ensure that you are transmitting or receiving the correct signal. Moreover, GNU Radio allows you to perform a wide range of operations such as Variable Variable Options ID: samp_rate ID: freq ID: top_block Value: 100M Generate Options: WX GUI Value: 5M

pulse shaping and developing modulation and demodulation schemes. By utilizing constellation diagrams, you can assess signals to ensure that modulation scheme errors are minimal and deterministic.

An eye pattern/diagram is a popular tool for assessing the signal performance of a RF system. This time domain visualization is generated by applying repetitively sampled digital data from a receiver to the vertical input and triggering the horizontal sweep using the data rate. The eye diagram is used for assessing various performance measures including inter-symbol interference, length

Some high performance SDR platforms such as Per Vices Cyan feature a Web user interface (UI) for configuring radio systems to ensure deterministic performance. This UI allows configuration of transmit chain, receive chain and clock board. In the receiver chain, this Web UI allows you to configure a wide range of parameters including synthesizer frequency, RFE receiver gain and attenuation. For the receiver DSP chain, it allows you to set various parameters including sampling rate, destination IP links and DSP NCO offset.

Using MIMO phased arrays helps to minimize interference and scattering and maximize data transmission rates. The deterministic latency of the FPGAs used in the implementation of MIMO systems help to enhance their overall performance. This deterministic performance also helps to enhance phase coherency in MIMO systems. The architecture of FPGAs also makes it easier to calculate phase coherency adjustments in applications such as radar. By utilizing GNU Radio, you can do visual phase alignment of inputs from different devices that form your MIMO system. All you need to do is select the synchronization settings of your devices using the UHD API and observe the outputs to know if the phases and frequencies are synchronized or not. Furthermore, you can set the timing source of your MIMO system by employing a UHD-based software program. Figure 2 shows a flow graph and an output graph for two channels that are not in phase. Adding a phase correction ensures that the two channels are aligned. High frequency trading (HFT) systems have strict latency requirements and demand networks with deterministic latency performance. The FPGAs used in SDRs have low latency making these radios ideal for developing modem cores for use in trading applications. In addition, the deterministic nature and highly parallel architecture of FPGAs make them an ideal solution for combating round trip latencies in trading systems. In HFT systems, FPGAs are used for executing compute-intensive portions of trading algorithms along with the modulation and demodulation of the data. 18

Modern wireless and cellular networks such as 5G, machine-to-machine (M2M) and Internet of Things (IoT) networks are time sensitive and demand components with minimal and deterministic latency. In the case of M2M networks, low latency and deterministic performance are required to ensure that message delivery times meet stringent timing constraints. Without deterministic performance, some features of M2M networks such as open loop automation control can be significantly affected. In addition, the reconfigurability of the FPGAs used in SDR platforms allows new wireless communication protocols and DSP algorithms to be implemented with ease. Conclusion Deterministic software tools exhibit a consistent performance and give the same results when provided with the same input. SDRs use software for a wide range of control and signal processing functions. Complex communication architectures can be realized by combining SDRs and software tools such as UHD and GNU Radio. In this article we have learned why software determinism is critical and how complex SDR solutions can be implemented by combining SDR and software. We have also learned some of the applications that demand deterministic performance.

SYSTEM DEVELOPMENT

Transforming 64-Bit Windows to Deliver Software-Only Real-Time Performance By Jeffery Hibbard, Chief executive officer - Intervalzero Next-generation industrial, vision, medical and other systems seek to combine high-end graphics and rich user interfaces with hard real-time performance, prioritization and precision. Today’s industrial PCs running 64-bit Windows, complemented by a separate scheduler on multicore multiprocessors, can deliver that precise real-time performance on software-defined peripherals. The pace of advancement in silicon integration and performance continues unabated, driven by the demands of ever-richer applications. That advancement, however, has been taking different directions, especially in the case of the integration of functionality onto single silicon dies. The task for the embedded OEM is to decide how to turn these revolutionary developments into real products that can provide what customers demand. That now includes high-definition audio and video, machine vision, real-time industrial products such as six-axis motion ontrol, real-time connectivity and a rich user interface. That user interface often must also include the ability to present complex realtime graphical data that is linked to the application in real time. Today’s hardware has that capability, but the way to realize it is through software. With processor cores that are powerful enough, there is no need to rely on custom hardware to implement specialized functions; that can now be done with software. Software can be more easily updated and improved than hardware, and it is here where OEMs can implement their real value. And the best way to smooth the task of implementing complex realtime software applications is to start with the right hardware environment. As noted above, hardware integration 20

COTS Journal | April 2022

has been taking different directions. On the one hand, there is a trend to integrate the kinds of devices used by real-time systems onto a single die. These might include a multicore processor, a DSP, an FPGA or an advanced graphics unit. We have recently seen, for example, devices that integrate processor cores and FPGAs, or processor cores with advanced graphics units that are also capable of intense number computation such as DSP. On the other hand, there is the opportunity to tap into today’s multi-core CPUs, whose tremendous power and performance is the result of multiple cores and, to a smaller extent, clock speeds approaching 3 GHz. These standard commercial off-the-shelf industrial PCs (IPCs) provide platforms that, with some additional performance, prioritization and precision. And with today’s CPUs, this processing can be done in floating point for more diverse calculations than with the fixed point typically found in a DSP. Such performance changes the focus from trying to optimize the use of every instruction to actually fully exploiting the real power of the multicore IPC. This trend has already resulted in devices that can outstrip traditional DSP processors. Another major development in this arena is the move to 64-bit architectures that are backward compatible with their 32-bit redecessors, but which offer enormously enhanced performance. This has several advantages, because even a highly integrated chip with different integrated functions with their different instruction sets and protocols throws up obstacles to a unified software environment, hich adds both hardware hurdles as well as burdens on the development team to circumvent them. The all-new implementation of IntervalZe-

ro’s RTX64 takes the latter path and transforms Windows into a fully functional real-time operating system that runs entirely on x64 multicore hardware. Additionally, in so doing it provides access to 128 Gbytes of non-paged memory, depending on actual mapped physical RAM size. Overall, Windows’ 512 Gbytes of physical memory dwarfs the 4 Gbytes physical memory limitation of 32-bit Windows. This vast amount of available memory opens the door to previously unavailable applications like MRI medical maging and high-end video editing to name a few. Above all, RTX64 provides a single commodity hardware environment in the form of multicore x64 devices. This enables a single software environment that can accommodate Windows with its rich user interface, available applications and development environment. And Windows is seamlessly connected to the full-function real-time symmetric ultiprocessing (SMP) RTX64 environment that can scale from 1 to 63 cores. Applications compile to a single code base with no need for FPGAs or DSPs to execute logic based on different code that must be separately compiled and linked with the main application. One set of hardware, one operating system environment, one set of tools and one base of code. That translates to one team that can communicate and work together and produce high-performance, scalable applications while dramatically shortening time-to-market. A Liberating Unified Architecture Freed from the isolation of the real-time system and from other functions such as the user interface, OEMs are able to explore more innovative solutions with less risk and overhead. For example, consider the user interface. Today’s advanced applications—and their users—are demanding feature-rich, interactive, touch-activated graphical user interfaces. Advanced


embedded systems are far beyond the headless systems of yesteryear. In addition, it is becoming increasingly important to provide a definitive user experience based on that interface, one that can help reinforce product branding. The old way of developing an embedded user interface was to have team design the UI on a desktop system using a graphics program such as Photoshop, Illustrator, or perhaps one of the later tools aimed at embedded systems. The result would be a prototype UI with simulated data and interfaces. That would then be handed off to the team developing the real-time application, and their task would be to implement the UI design under whichever RTOS environment they were using. This inevitably entailed changes and compromises, and testing that was mostly put off until late in the development cycle with predictable effects on time-to-market. Using RTX64, development teams can build their UI with whichever Windows-based tools they choose and be confident that the objects in the interface can communicate directly with the RTX64 APIs, and xchange commands

and data with the embedded application. Any changes to the UI or to the embedded functionality can be quickly traced and updated between the two. The same seamless access to networking, databases and storage can be provided for hard real-time applications under RTX64 because it does not alter Windows in any way, but is a real-time extension to Windows. Thus its communications with Windows are seamlessly integrated and do not depend on mechanisms like remote procedure calls, virtualization, or hypervisors that are associated with other implementations of multiple operating systems. The addition of a second scheduler and an RTOS infrastructure allows UI functions to execute in Windows while real-time functions execute on the RTX scheduler. Putting the right task on the right cheduler delivers the best overall result.

rich user interfaces, all place demands that can only be met by advanced 64-bit systems that can include the rich user interface possible with Windows along with the high performance of a 64-bit RTOS.

RTX64—A Fresh Start into 64-Bit The new RTX64 was built from the ground up to open the world of 64-bit real-time computing, and it is not a port of the 32-bit product. Professional audio and video, high-end medical devices along with advanced industrial control systems that incorporate machine vision and

To start with, RTX64 has a hardware abstraction layer (HAL) that is distinct from the Windows HAL, but operates alongside it. Thus, from the start, no modification of Windows is needed. The two systems operate side-by-side and communicate via existing mechanisms. The RTX64 HAL can scale from 1 to 63 cores to deliver deterministic realtime performance with timing down to 1 μs (dependent on hardware support). The scheduler, which resides in the RTX64 real-time subsystem (RTSS), can assign threads to cores to achieve symmetrical multiprocessing (SMP) without relying on virtualization or complex interprocess communications.

RTX64 provides an architecture that takes advantage of the advancing echnologies—specifically, high-speed, multicore x64—that can outperform and outscale the traditional embedded environment that relies on DSPs, FPGAs and microcontrollers (Figure 1). It does this by implementing their functions at even higher performance in a single hardware environment. And it can do this in conjunction with Windows, which offers the rich user environment and access to a huge number of applications that can take advantage of and support the real-time operations.

This is also a result of the vast memory space that is available to all cores without memory partitioning. Up to 128 Gbytes of non-paged memory and up to 512 Gbytes of physical memory can be accessed by he entire system. This is a huge advantage for medical applications that increasingly depend on visualization such as the Optical Coherence Tomography (OCT) technology now under development, or for real-time surgical robots that depend on accurate rendering and processing of organ images like a beating heart. It is essential for advanced industrial control systems that must not only present visual data to the user, but also process it in real time to drive motion control of tools and also for he inspection of parts produced by the process.

Figure 1: RTX64 provides an architecture that takes advantage of the advancing technologies—specifically, highspeed, multicore x64—that can outperform and outscale the traditional embedded environment that relies on DSPs, FPGAs and microcontrollers.

Having a memory space like this available to such a high-performance general-purpose hardware platform allows OEMs to develop specialized oftware that can perform extremely specialized functions that would ave otherwise required specialized hardware components. Experience has shown that mixing different hardware involves quite different sets of software that depend on different disciplines (e.g., C++ COTS Journal | April 2022

vs. Verilog), which not only greatly slows development time, but also places limits on performance and scalability. Scaling such systems only brings increased complexity with each disparate piece of additional hardware with its own interfaces and unique software needs. The RTX64 real-time subsystem (RTSS), which includes a real-time scheduler, is fully independent from the Windows kernel and the Windows scheduler. There is no inherent interaction or interference of Windows and real-time threads. Only intended communications between threads by the developer can occur using the real-time API. A real-time API is provided for use with user-mode Windows applications, or a real-time kernel API for use with Windows kernel drivers. In scenarios such as those enabled by RTX64, applications can present themselves to the user as common Windows applications, while behind the user interface, many of their features are taking advantage of RTX64 real-time processes. For example, a machine tool control program might present a view of the part being machined along with controls and settings that the user can access via a touch screen. However, the actual application consists of two parts. The Windows program can communicate with the real-time control program on two levels— the kernel and the user level—by means of real-time APIs. At the kernel level, a Windows driver can send data to the RTX64 side, which is perhaps controlling the travel of a tool, and receive current position data, which it then passes to the user interface, or subjects to some sort of processing via a real-time kernel API (RtkApi). At the user level, the operator can set values or the position of switches, etc., on the touch screen and these will communicate with a Windows process. That process in turn uses the real-time API (RtApi) to communicate with the RTSS. These two classes of API communicate directly with the RTSS, which is where the real-time control program resides. As the demand for rich user interfaces for real-time and embedded systems continues to grow, developers are being faced with the dilemma of how to link such interfaces with RTOS environments that are traditionally not designed to support complex user interfaces. We have already mentioned the often-awkward tricks that must be performed to match such an RTOS-based system to a complex user interface.With the RTX64 extension to Windows, it is straightforward to use one’s favorite graphical tools to design a user interface that can link directly to the underlying real-time application 22

COTS Journal | April 2022

Figure 2: Another approach to AMP is to implement virtualization with a hypervisor, which is a separate layer of software running directly on the hardware that divides the hardware among the operating systems.

using the RTX APIs. Even more attractive to some could be the ability to simply purchase an off-the-shelf software control and data acquisition (SCADA) tool, which comes with many pre-designed but customizable gauges, sliders, switches and representations of pumps, tanks, actuators, etc., and develop from there using the same RTX64 APIs to hook up to the system. The same goes for video data. There is a wide selection of tools and applications that can represent physical phenomena, such as heat distribution, fluid dynamics, stress and more, and they all run under Windows. Image processing applications exist that can do edge detection and other operations needed for parts inspection. The list goes on. The OEM has, at this level of the Windows user interface, a rich selection of “build or buy” options, all of which he can confidently use and/or experiment with knowing that the interface to the underlying real-time application is well-defined and will work out of the box. SMP Paves the Way to Performance and Scalability There are, of course, different schools of thought on how to take advantage of multicore processors. These basically break down into symmetrical multiprocessing (AMP), or virtualization and symmetrical multiprocessing (SMP). One approach to AMP requires that a copy of the perating system run on each of the cores. This then requires assignment if memory to the individual cores and brings with it the need for interprocess communications that add to overhead. If one tries to implement a user interface with Windows the same inefficiencies apply, equiring interprocess communications between Windows and multiple instantiations of RTOSs and memory partitions. Then try processing (under the RTOS) and displaying (under Windows) real-time video data in such a system—involving more IPC—and things clog up very quickly. Scaling the system to more

cores requires more copies of the RTOS, more memory partitioning and reconfiguration of the application. Another approach to AMP is to implement virtualization with a hypervisor, which is a separate layer of software running directly on the hardware that divides the hardware among the operating systems (Figure 2). ome multicore processors even have built-in hardware assistance for virtualization, which basically presents a virtual “motherboard” to each perating system. Virtualization is often used to support “separation kernels,” which are isolated from the rest of the system, communicating only via tightly controlled mechanisms and protocols. This can be useful in certain cases, but its goal is isolation, whereas the goal of SMP is integration. Again, the isolation extends to the user interface, which is running on its own virtual processor or motherboard and must communicate with processes running on other cores via interprocess communications and remote procedure calls, but now also through the hypervisor, which adds even more latency. Additionally, AMP systems have a scheduler for every virtualized operating system. This means additional communication and synchronization that rapidly becomes hugely complex. RTX64 represents a real-time operating system extension to Windows and works with Windows as a single operating system environment that uses the SMP approach to treat the multiprocessor hardware as a single shared resource. It requires only a single copy of the entire operating system environment including the real-time subsystem with its real-time scheduler that has access to all cores assigned to the subsystem (Figure 3). Unlike with AMP, the code can be written once and can be later scaled as functions are added by statically reassigning threads or adding cores and reparti-


systems. A single cable can carry multiple control channels along with safety signals with Safety Inspection Level (SIL) 3 certification. In addition, multiple cores can be dedicated to EtherCAT functionality for truly rich control connectivity, all without the expense and power consumption of additional specialized hardware.

tioning. Since all the cores, and hence all the threads, have direct access to shared data and all resources are visible to all real-time processes, there is no need for additional copies or the use of complex interprocess communications schemes or remote procedure calls. The ability to use a single extended operating system environment across a homogenous hardware platform reduces the OEM’s major hardware decision to, “Do I have enough cores to do what I need to do?” or, “How many more cores do I need to add in order to scale this application to the additional functionality I need?” It no longer involves bridging interfaces between disparate hardware elements like FPGAs and DSPs, or adapting code to parts with increased performance but different programming needs. It no longer involves bringing in different hardware specialists to create or upgrade a product. The team defines the performance in terms of a single programming language like C++. And that leads to the additional advantage of having a single set of development tools, such as Windows Visual Studio, for the entire project.Windows serves as the development environment for the entire system—Windows functions as well as real-time coding. And other Windows-based tools can be brought into the mix as well, such as requirements analysis, version control or static analysis tools to name a few. The user mode of the real-time subsystem also includes an RTX64 server console that connects to the RTSS. The real-time crew can also use their favorite real-time debuggers, profilers and analyzers to tweak the real-time subsystem. And they can all communicate and consult with each other in the same terms. Nobody has to learn Verilog or a DSP coding language. Connectivity—Internet and Real Time With the rise of the Internet of Things, connectivity has become a musthave in terms of linking devices to local networks, then to serv-

ers and ultimately to the Cloud. Internet connectivity is simply a given with Windows, and it can be customized to exchange data and commands with the real-time processes as well as provide for a remote user interface for interacting with the systems from virtually anywhere. However, the Windows Internet connection itself is not real time. Yet with the same systems running Windows and the RTX64 real-time extension environment, it is possible to add real-time Ethernet connectivity in the form of EtherCAT, which is an Ethernet-based fieldbus system for control automation technology (CAT) as shown in Figure 4. EtherCAT also provides for gateways to integrate existing fieldbus components such as CANopen or Profibus. EtherCAT runs under RTX64 in software without the need for any specialized EtherCAT card plugged into the system bus. Running on one or more processor cores, EtherCAT communicates directly with whatever network interface chip (NIC) is used in the system. The individual device can be selected during EtherCAT configuration.

IntervalZero’s RTX64 has opened the world to Windows-based real-time systems with highend vision, visualization and rich user interfaces. It has done this by giving the developer the ability to transform the functions of hardware components into software components by harnessing the power of the underlying multicore processing hardware. For the OEM, there is nothing to inventory and the parts can be replicated infinitely. For the software team, there is no need for specialized knowledge of hardware such as DSPs and FPGAs. The code exists in a unified code base and can be managed as such. RTX64 integrates seamlessly into the Microsoft Visual Studio Integrated Development Environment, and deploys to a single integrated Windows system. It extends Windows, delivering hard real-time precision with bounded latency, and it does so with multicore processors as a scalable natively SMP-enabled solution. Its positive effects on cost, time-to-market, inventory, user experience and raw system performance are revolutionary.

COTS Journal | April 2022

“The design of the INTEGRITY-178 tuMP RTOS to high-robustness security and Common Criteria EAL 6+ complements the wide range of security features built into the SBC3511 hardware and firmware designed to assist with the prevention of exploitation of critical technologies and data,” said Pete Thompson, Abaco’s VP of Product Management. “The combination of advanced security, high-performance, and leading-edge thermal management on the SBC3511 enables the joint solution to meet the demanding requirements of security-critical avionics systems.” The SBC3511 3U OpenVPX rugged single board computer derives its high performance from the new, highly integrated Intel Xeon E-2276M 6-core/12-thread processor ( formerly known as Coffee Lake Refresh) operating at 2.8GHz with TurboBoost up to 4.5GHz. It also features a 40 Gigabit Ethernet data plane, delivering a high-speed interconnect aligned with the SOSA I/O intensive profile for maximum multi-vendor interoperability. The SBC3511 utilizes an onboard Xilinx® Zynq® UltraScale+™ MPSoC with built-in security capabilities. It can be utilized to instantiate a range of Abaco-defined security features or by customers to embed application-specific features. Support is also provided for Intel’s Trusted Execution Technology. The INTEGRITY-178 tuMP high-assurance RTOS is designed to meet the strictest requirements for both airborne safety and security simultaneously, including RTCA/DO-178B/C design assurance level

(DAL) A and the SKPP for High Robustness. INTEGRITY-178 tuMP is a multicore RTOS with support for running a multi-threaded DAL A application across multiple processor cores in symmetric multi-processing (SMP) or bound multi-processing (BMP) configurations. INTEGRITY-178 tuMP is the only RTOS to be part of a multicore certification to DO-178C and CAST-32A. INTEGRITY-178 tuMP was the first RTOS to be certified conformant to the FACE Technical Standard, edition 3.0, and it is the only RTOS with multicore interference mitigation for all shared resources. That bandwidth allocation and monitoring (BAM) functionality ensure that critical applications meet their required deadlines, significantly lowering integration and certification risk. The INTEGRITY-178 RTOS is the only commercial operating system ever certified to the Separation Kernel Protection Profile (SKPP) published by the Information Assurance Directorate of the U.S. National Security Agency (NSA). That certification was done by the National Information Assurance Partnership (NIAP) to Common Criteria EAL 6+ “High Robustness,” and included all the functionality required to run multi-level security (MLS) applications, such as cross-domain solutions (CDS). INTEGRITY-178 tuMP is also the only RTOS to be part of certification to NSA’s “Raise the Bar” standards for cross-domain solutions. Abaco Systems, Inc. www.abaco.co
