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

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.

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

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.

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

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

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

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

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

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.
