<P> By the late 1960s , designers were striving to integrate the central processing unit ( CPU ) functions of a computer onto a handful of MOS LSI chips , called microprocessor unit ( MPU ) chipsets . Building on an earlier Busicom design from 1969 , Intel introduced the first commercial microprocessor , the 4 - bit Intel 4004 , in 1971 , followed by its 8 - bit microprocessor 8008 in 1972 . In 1969 , Lee Boysel , b 8 - bit arithmetic logic units ( 3800 / 3804 ) he designed earlier at Fairchild , created the Four - Phase Systems Inc . AL - 1 , an 8 - bit CPU slice that was expandable to 32 - bits . In 1970 , Steve Geller and Ray Holt of Garrett AiResearch designed the MP944 chipset to implement the F - 14A Central Air Data Computer on six metal-gate chips fabricated by AMI . </P>
