The PowerPC 620 microprocessor in distributed computing

摘要

PowerPC 620 microprocessor was developed with distributed computing in mind. Several design techniques found in distributed applications have been employed in designing the processor core as well as the processor-system interface. Superscalar and speculative execution are two key implementation factors that push the processor performance to a new height. The processor is a 64-bit implementation of the PowerPC Architecture specification and is designed for high-end workstation and server markers. Application of PowerPC 620 microprocessor in a multimedia workstation and a multimedia server will be discussed in details.
