PA-RISC is an instruction set architecture (ISA) developed by Hewlett-Packard. As the name implies, it is a reduced instruction set computer (RISC) architecture, where the PA stands for Precision Architecture.The design is also referred to as HP/PA for Hewlett Packard Precision Architecture.he HP 9000 machines were soon upgraded with the PA-RISC processor as well, running the HP-UX version of UNIX. Other operating systems ported to the PA-RISC architecture include Linux, OpenBSD, NetBSD and NEXTSTEP. An interesting aspect of the PA-RISC line is that most of its generations have no Level 2 cache.
