PowerPC Computers
PowerPC (with the backronym Performance Optimization With Enhanced RISC – Performance Computing, sometimes abbreviated as PPC) is a reduced instruction set computer (RISC) instruction set architecture (ISA) created by the 1991 Apple–IBM–Motorola alliance, known as AIM. PowerPC, as an evolving instruction set, has been named Power ISA since 2006, while the old name lives on as a trademark for some implementations of Power Architecture–based processors. Originally intended for personal computers, the architecture is well known for being used by Apple's desktop and laptop lines from 1994 until 2006, and in several videogame consoles including Microsoft's Xbox 360, Sony's PlayStation 3, and Nintendo's GameCube, Wii, and Wii U. PowerPC was also used for the Curiosity and Perseverance rovers on Mars and a variety of satellites. It has since become a niche architecture for personal computers, particularly with AmigaOS 4 implementations, but remains popular for embedded sys ...

AIM Alliance
The AIM alliance, also known as the PowerPC alliance, was formed on October 2, 1991, between Apple Inc., Apple, IBM, and Motorola. Its goal was to create an industry-wide open-standard computing platform based on the IBM POWER architecture, POWER instruction set architecture. It was intended to solve legacy problems, future-proof the industry, and compete with Microsoft's monopoly and the Wintel duopoly. The alliance yielded the launch of Taligent, Kaleida Labs, the PowerPC CPU family, the Common Hardware Reference Platform (CHRP) hardware platform standard, and Apple's Power Macintosh computer line. History Development From the 1980s into the 1990s, the computer industry was moving from a model of just individual personal computers toward an interconnected world, where no single company could afford to be vertically isolated anymore. ''Infinite Loop (book), Infinite Loop'' says "most people at Apple knew the company would have to enter into ventures with some of its erstwhile e ...

Power Architecture
Power ISA is a reduced instruction set computer (RISC) instruction set architecture (ISA) currently developed by the OpenPOWER Foundation, led by IBM. It was originally developed by IBM and the now-defunct Power.org industry group. Power ISA is an evolution of the PowerPC ISA, created by the mergers of the core PowerPC ISA and the optional Book E for embedded applications. The merger of these two components in 2006 was led by Power.org founders IBM and Freescale Semiconductor. Prior to version 3.0, the ISA is divided into several categories. Processors implement a set of these categories as required for their task. Different classes of processors are required to implement certain categories, for example a server-class processor includes the categories: ''Base'', ''Server'', ''Floating-Point'', ''64-Bit'', etc. All processors implement the Base category. Power ISA is a RISC load/store architecture. It has multiple sets of registers: * ''32'' × 32-bit or 64-bit general-pu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
