3. First microprocessor developed by Intel in 1971, called Intel 4004. Later different generations of microprocessors were developed. Evolution of Microprocessors 3

4. Intel Corporation introduced 4004, the first microprocessor in 1971. During the same period: Rockwell International’s PPS-4 ( 4 bits ) Intel’s 8008 ( 8 bits ) National Semiconductor’s IMP-16 ( 16 bits ) They were fabricated using PMOS technology. They were not compatible with TTL. First Generation Microprocessors 4

5. Some applications are: Calculators Game machines Home appliances Accounting system First Generation Microprocessors 5

6. Marked the beginning of very efficient 8-bit microprocessors. Some of the popular microprocessors were: Motorola’s 6800 and 6809 Intel’s 8085 Zilog’s Z80 They were manufactured using NMOS technology. This technology offered faster speed and higher density than PMOS. TTL compatible. Second Generation Microprocessors 6

7. Some applications are: Instrumentation Process control systems Communication preprocessors Military applications Intelligent terminals Second Generation Microprocessors 7

8. This age dominated by 16-bits microprocessors. Some of them were: Intel’s 8086/80186/80286 Motorolla’s 68000/68010 They were designed using HMOS technology . Third Generation Microprocessors 8

9. Some applications are: Business and data processing applications Sophisticated real time control Advanced communications Distributed processing networks Third Generation Microprocessors 9

10. This era marked the beginning of 32 bits microprocessors. Intel introduced 432, which was bit problematic. A clean Intel 80386 was launched. Motorola introduced 68020/68030. They were fabricated using low-power version of the HMOS technology called HCMOS. Fourth Generation Microprocessors 10

11. Some applications are: Multi user, multi function environments Office information equipments Fourth Generation Microprocessors 11

12. Design surpassed 10 million transistors per chip. Processing speed increased tremendously. A microprocessor with 1GHz clock can execute 2000 million instruction per second. Intel leads the show here with Pentium, Celeron and very recently dual and quad core processors working with up to 3.5GHz speed . Fifth Generation Microprocessors 12
