is a broad term to describe similar RISC instruction sets
developed and manufactured by such companies as IBM
and P.A. Semi
. The governing body is Power.org
, comprising over 40 companies and organizations.
The term "Power Architecture" should not be confused with IBM's different generations of "POWER architectures

Power Architecture began its life at IBM in the late 1980s when the company wanted a high-performance RISC architecture for their mid-range workstations and servers. The result was the "POWER architecture
." Its first implementation was featured in the RS/6000
computers introduced in 1990. This was the 10-chip RIOS-1 processor, later called POWER1
. The RISC Single Chip
(RSC) processor was developed from RIOS-1.
In 1992, Apple
, IBM and Motorola
formed the AIM alliance
to develop a mass market version of the POWER processor. The result of this was the "PowerPC......
