Intel’s ) 8085 microprocessor is an 8 bit microprocessor. Some of the popular processors were: ĩ Motorola’s 6800 and ) The 6800 was an 8-bit microprocessor 2) The 6800 has a 16-bit address bus that could directly access 64 KB of memory 3) The Motorola 6809 is an 8-bit (with some 16-bit features)microprocessor 4) 6809 were the use of two 8-bit accumulator.ġ0 Intel’s 8085 1) 8085 microprocessor is an 8 bit microprocessor 6) 4-bit words.ĥ Rockwell International’s PPS-4 (4 bits) The Rockwell PPS-4 (aka PPS-4/1) was a 4-bit microprocessor designed by Rockwell International and first produced at the 3rd quarter of 1972. The chip came in a 42-pin quadruple in-line packageĦ Intel’s 8008 (8 bits) 1) 8-bit microprocessor 2) Up to 800 KHz 3) 16 KB memory 4) 7-level deep stack 5) 8 In / 24 Out portsħ National Semiconductor’s IMP-16 (16 bits) ) 16-bit microprocessor 2) The IMP-16 provided four 16-bit accumulatorsĨ Second Generation (1974 – 1978) Marked the beginning of very efficient 8 – bit microprocessors.

National Semiconductor’s IMP-16 (16 bits)Ĥ Intel 4004 1) Maximum clock speed of 740 kHz.Rockwell International’s PPS-4 (4 bits).There were three other microprocessors in the market during the same period: We divide the years of development of microprocessors as 5 generationsģ First generation (1971 – 73) Intel Corporation introduced 4004 PRESENTED BY: S.UMER HUSSAIN (294) ABDUL WAHAB (333) NOMAN ASLAM (307) MUSTAFA HAMID (206)Ģ Introduction: Microprocessor is an integrated circuit that contains all the functions of a central processing unit of a computer.
