Power Architecture is a registered trademark for similar RISC instruction sets for microprocessors developed and manufactured by such companies as IBM, Freescale, AMCC, Tundra 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" where the former is a broad term including all products based on newer POWER, PowerPC and Cell processors, and the latter is a deprecated instruction set for IBM RISC processors of the 1990's, replaced by the PowerPC/Power ISA derivative of the POWER ISA. Power Architecture is a family name describing processor architecture, software, toolchain, community and end-user appliances and not a strict term describing specific products or technologies.
