Single chip
microprocessor was introduced by Intel in 1971, called Intel 4004. Before this,
few hundreds of transistors were used and placed on a circuit board and then
few numbers of these boards were used as processor. It was 4-bit processor
which actually revolutionized the embedding system. Microprocessor increased
the reliability as the design was simplified and there were few electrical
connections. Then in 1972, Intel came up with the world’s first 8-bit processor
Intel 8008. But the Intel 8080, introduces in 1974, became the integral part of
personal computer and was used in MITS Altair 8800 computer and machines
running CP/M operating System. In 1976 Intel introduced 16-bit 8086 processor
which was later used to devise 8088 by IBM for the first PC. Major breakthrough
can be dedicated to Pentium which was released in 1993, which had a speed of 60
MHz and could process data like images, handwriting, voice etc. In 2006 Intel
come up with core Processor, which has speed of 1.6 GHz and consist of multiple
cores.
