![]() ![]() Intel 8080 was the first commercially popular 8bit microprocessor. This was soon followed by Intel 8080, also an 8-bit microprocessor. Intel 8008 was the next in the evolution, the first 8-bit microprocessor. ![]() However, it found applications in controlling devices. So, it was not really of practical use for arithmetic calculations. In 1971, INTEL created the first microprocessor 4004 that would run at a clock speed of 108 KHz.With only 4 bits as the word size, the 4004 could only represent signed numbers in the range -8 to +7, which is indeed very small. This was the period during 1971 to 1973 of microprocessor’s history. Generation of Microprocessor 1st Generation It has ALU (arithmetic and logic unit), a control unit, registers, bus systems and a clock to perform computational tasks. A microprocessor is also known as a central processing unit in which numbers of peripherals’ are fabricated on a single chip. In 1971, the first microprocessor Intel 4004 was invented. ![]() In 1968, Gordan Moore, Robert Noyce and Andrew Grove resigned from the Fair child semiconductors and started their own company: Integrated Electronics (Intel). Fair child semiconductors (founded in 1957) invented the first Integrated Circuit in 1959 that marked the microprocessor history. ![]()
