HOW MICROPROCESSOR EVOLVED OVER THE YEARS?
Microprocessor is a computer processor that incorporates the functions of a central processing unit on a single integrated circuit. Andrew Grove, Gordan Moore, and Robert Noyce created the first microprocessor, Intel 4004. First Generation In 1971, microprocessors were introduced as the first generation systems. Intel created 4004 microprocessor which has 108 KHz clock speed. It was a 4-bit processor and perform basic arithmetic calculations.
Second Generation In 1973, second generation microprocessors were introduced by Intel. They are 8-bit processor such as INTEL-8085. It is based on NMOS technology and had super fast speed.
Third Generation In third generation 16-bit processors are invented using HMOS technology. It contained 29,000 transistors and originally ran at the speed of up to 5MHz. The third generation microprocessors worked like mini-computers.
Fourth Generation In fourth generation, it is witnessed twith development of 32-bit microprocessors using HCMOS fabrication. They used VLSI technology which had about 5000 transistors along with other circuits.
Fifth Generation In fifth generation, there are many advancements including high-performance and high-speed that use 64-bit microprocessors. Some few examples are Celeron, Pentium, Dual and Quad-core processor.
