Evolution of Microprocessors

Transistor was invented in 1948 (23 December 1947 in Bell lab). IC was invented in 1958 (Fair Child Semiconductors) By Texas Instruments J kilby. First microprocessor was invented by INTEL(INTegrated ELectronics).  Size of microprocessor –  4 bit  Name Year of Invention Clock speed Number of transistors Inst. per sec INTEL 4004/4040 1971 by Ted Hoff and Stanley Mazor 740 KHz 2300 60,000 Size of microprocessor –  8 bit    Name Year of Invention Clock speed Number of transistors Inst. per sec 8008 1972 500 KHz 3500 50,000 8080 1974 2 MHz 6000 10 times faster than 8008 8085 1976 (16 bit address bus) 3 MHz 6500 769230 Size of microprocessor –  16 bit  Name Year of Invention Clock speed Number of transistors Inst. per sec 8086 1978 (multiply and divide instruction, 16 bit data bus and 20 bit address bus) 4.77 MHz, 8 MHz, 10 MHz 29000 2.5 Million 8088 1979 (cheaper version of 8086 and 8 bit external bus)     2.5 Million 80186/80188 1982 (80188...

EVOLUTION OF MICROCONTROLLER

     The Micro controller was developed by Intel in 1980. The 8051 is one of the most popular 8 bit micro controllers and combines an instruction set that allows tight coding of small particularly I/O application with enough power and a large enough program space that it can be used with C Language.     The last decade has seen an exciting evolution with capabilities of microprocessors. The development of 16 and 32 bit microprocessors contributed  to the growth of powerful personal computers that are used in all walks of life. Because of their processing power and speed, these 16 and 32 bit microprocessors have also found their way into the design of standalone products such as electronic instruments which require sophisticated control capability. In the evolution of microprocessor capability, instead of focusing upon larger word widths and address spaces. the present emphasis 'is upon exceedingly fast real time control. The development of microcontrollers...

Recent Trends in Embedded Industry

Image
     By the year 2027, it is estimated that the global embedded system market is expected to reach USD 127.50 billion. Embedded systems are vital parts of the world right from computers to airplanes. They are used in many critical systems that we also rely on for our daily needs. The market for  embedded systems  is growing due to the increasing dependence on digital devices at an aggressive pace.      As the embedded systems are highly customizable, they enable greater flexibility for the new applications for many industries. The telecommunication industry has one of the biggest market shares of embedded systems applications as they are tremendously applied in the networks related to wireless communications.  In the year 2019, the segment of microcontrollers also have the largest share of the embedded system market. Embedded systems will be of high importance not only for mobile devices and networks but also for real-time applications. The p...
