This paper describes the architectural extensions to the PA-RISC 1.1 architecture to enable 64-bit processing of integers and pointers. It also describes MAX, the Multimedia Acceleration eXtensions which speed up the processing of multimedia and other applications with parallelism at the intra instruction, or subword, level. Other additions to the PA-RISC 2.0 architecture include performance enhancements with respect to memory hierarchy management, branch penalty reduction, and floating-point performance.
