The Power PC 601 microprocessor

The PowerPC 601 microprocessor, the first of a family of processors based on the PowerPC architecture, is described. The general-purpose processor contains a 32-Kb cache and a superscalar machine organization that allows dispatch and execution of up to three instructions each clock cycle. The bus interface and storage control mechanisms can be configured for a wide range of system designs, from low-cost desktop personal computers to high-performance multi-processor systems. The PowerPC architecture, machine organization, chip packaging technology, and performance are discussed. >
