= PPC (Power Performance Chip) процессор PowerPC семейство 32- и 64-разрядных микропроцессоров, разработанных альянсом IBM, Motorola и Apple Computer. Объявлено в 1993 г. Широко применяются в компьютерах PowerMac (Apple Computer), RS/6000 и AS/400 (IBM). Базируется на RISC-архитектуре Смотри также: CPU
(PPC) A RISC microprocessor designed to meet a standard which was jointly designed by Motorola, IBM, and Apple Computer (the PowerPC Alliance). The PowerPC standard specifies a common instruction set architecture (ISA), allowing anyone to design and fabricate PowerPC processors, which will run the same code. The PowerPC architecture is based on the IBM POWER architecture, used in IBM's RS/6000 workstations. Currently IBM and Motorola are working on PowerPC chips. The PowerPC standard specifies both 32-bit and 64-bit data paths. Early implementations were 32-bit (e.g. PowerPC 601); later higher-performance implementations were 64-bit (e.g. PowerPC 620). A PowerPC has 32 integer registers (32- or 64 bit) and 32 floating-point (IEEE standard 64 bit) floating-point registers. Support for running in little-endian mode. Addition of single precision floating-point operations. Control of branch prediction direction. See also PowerOpen, PowerPC Platform (PReP).
