Still Using Aging PA-RISC Hardware? Discover the future
What is PA-RISC? PA-RISC (Precision Architecture-Reduced Instruction Set Computing) is a microprocessor architecture implemented by Hewlett-Packard (HP) in the mid-1980s. It is designed to improve performance and efficiency using a simplified instruction set.
PA-RISC 1.0 and PA-RISC 1.1 versions of the architecture are denoted PA1 in the rest of this paper. In section 2 below, the design requirements for PA2 are outlined. In section 3, we describe the 64-bit exten-sions for both data and addresses. …
PA-RISC Processors History and Performance – OpenPA.net
PA-RISC processors and HP changed significantly during the 1990s, from design philosophy to production processes. PA-RISC processors and chipsets for HP 9000 had been designed and fabricated by HP in its own plants and design labs for decades.
