1 HISTORY OF MICROPROCESSORS Gursharan Singh Tatla 1

2 HISTORY OF MICROPROCESSORS  Fairchild Semiconductors (founded in 1957) invented the first IC in  In 1968, Robert Noyce, Gordan Moore, Andrew Grove resigned from Fairchild Semiconductors  They founded their own company Intel (Integrated Electronics).  Intel grown from 3 man start-up in 1968 to industrial giant by  It had 20,000 employees and $188 million revenue. 2 Gursharan Singh Tatla m

3 I NTEL 4004  Introduced in  It was the first microprocessor by Intel  It was a 4-bit MP. 3 Gursharan Singh Tatla m
