The 21064 microprocessorThe 21064 microprocessor mounted on a business card
The Alpha 21064 is a microprocessor developed and fabricated by Digital Equipment Corporation that implemented the Alpha (introduced as the Alpha AXP) instruction set architecture (ISA). It was introduced as the DECchip 21064 before it was renamed in 1994. The 21064 is also known by its code name, EV4. It was announced in February 1992 with volume availability in September 1992. The 21064 was the first commercial implementation of the Alpha ISA, and the first microprocessor from Digital to be available commercially. It was succeeded by a derivative, the Alpha 21064A in October 1993. This last version was replaced by the Alpha 21164 in 1995.
