Abstract
This paper details the 64-bit PowerPC Architecture specification. It compares and contrasts the 32-bit subset specification against the full 64-bit specification. Architecture, application OS, and hardware implications of the 64-bit specifications are all explored in detail. In addition, 32- and 64-bit compatibility and OS migration strategies are described. The PowerPC 620 microprocessor implementation is used as a vehicle when examining the 64-bit features. The 620´s MMU is described, and potential performance implications are discussed.
