  • Abstract
    The PowerPC is a new RISC architecture derived from IBM´s POWER architecture. The changes made to POWER simplify implementations, increase clock rates, enable a higher degree of superscalar execution, extend the architecture to 64 bits, and add multiprocessor support. For compatibility with existing software, the developers retained POWER´s basic instruction set, opcode assignments, and programming model.<>
