The intel 8088 is a high performance microprocessor implemented in nchannel, depletion load, silicon gate technology hmos ii, and packaged in a 40pin cerdip package. The intel m80c86 is a high performance, chmos version of the industry standard hmos m8086 16bit cpu. It is a softwarebinary compatible with the morefamous intel 8080 with only two minor instructions added to support its added interrupt and serial inputoutput features. Vinco services 204, savitri sadani, 11, community centre, preet vihar, delhi110092. Or as intel engineer and 8086 designer stephen morse once put it, the 8088 was a castrated version of the 8086. The 8086 also called iapx 86 is a 16bit microprocessor chip designed by intel between early 1976 and june 8, 1978, when it was released.
The intel 8088 microprocessor was a variant of the intel 8086 and was introduced on july 1, 1979. It was released in 1979 and has identical architecture to the intel 8086, with the exception of a reduced external data bus width size from 16bit to 8bit. Intel 8086 microprocessor is the enhanced version of intel 8085 microprocessor. The processor has attributes of both 8and 16bit microprocessors. Intel 8088 has the same alu,same registers and same instruction set as the 8086.
Both processors have the same architecture, and the only difference of the 8088 cpu from the 8086 is the external data bus width it was reduced from 16 bits to 8 bits. Introduced on july 1, 1979, the 8088 had an 8bit external data bus instead of the 16bit bus of the 8086. It had an 8bit external data bus instead of the 16bit bus of the 8086. The intel 8088 is a high performance microprocessor implemented in nchannel depletion load silicon gate technology hmosii and packaged in a 40pin cerdip. But the only difference is 8088 has only 8bit data bus and 20bit address bus. Intel 8086 is built on a single semiconductor chip and packaged in a 40pin ic package.
