Here, we will discuss about short note on evolution of microprocessor, and further Microprocessor evolution is divided into five generation, and every generation are described below.įirst generation of microprocessor was introduced by Intel from 1971 – 1972.Those types of microprocessors are capable only to processed in serially of all instructions. Later, Intel was designed other new 8087 microprocessor that was first math co-processor, and this processor was embedded into IBM PC.ĭue to more effort of microprocessor’s companies, other new processor are come in market such as 8088,80286,80386,80486,Pentium II, Pentium III, Pentium IV and now Core 2Duo,Dual Core and Quad core processors.

Floating point means to decimal number such as (456.23). Given to all microprocessor were not supportable for Floating point instructions. 8086 microprocessor is better to 8085 because it is based on 16 bit. In 1976, Intel was announced again new 8086 microprocessor. In 8085 microprocessor, are attached two Enable/Disable Instructions, 3 interrupt pins and serial I/O pins. In 1976, Intel was designed 8085 processor but it was not new invention because 8085 microprocessor was updated version of 8080 microprocessor. Intel was announced new Intel’s 8080 in 1974 for personal computer. Intel 4004 was able to perform only addition/subtraction operation on 4 bit at once.

Intel 4004 is based on 4 bit processor due to this it was not more popular. History of Microprocessor – Here, we spread the light on brief history of microprocessor.įirst microprocessor was developed by INTEL in 1971, and its name was Intel 4004.
