- PA-RISC family - PA-RISC is a microprocessor architecture developed by Hewlett-Packard's Systems
- Reduced instruction set computer - The reduced instruction set computer (RISC, pronounced like "risk") is a CPU design philosophy that favors an instruction set reduced both in size and complexity of addressing modes, in order to enable easier implementation, greater instruction level parallelism, and more efficient compilers. As of 2007, common RISC microprocessors families include the DEC Alpha, ARC, ARM, AVR, MIPS, PA-RISC, Power Architecture (including PowerPC), and SPARC.
- Link register - A link register, in many CPU architectures such as the PowerPC, ARM, and the PA-RISC, is a special purpose register which holds the address to return to when a function call completes. Other architectures (such as SPARC) have a register with the same purpose but another name (in this case, "output register 7").
- Convex Computer - Convex Computer was a company that produced a number of vector minisupercomputers, supercomputers for small-to-medium-sized businesses. Their later Exemplar series of parallel computing machines were based on the Hewlett-Packard PA-RISC CPU series, and in 1995, HP bought the company.
- HP-UX - HP-UX (Hewlett Packard UniX) is Hewlett-Packard's proprietary implementation of the Unix operating system, based on System V (initially System III). It runs on their PA-RISC range of processors and Intel's Itanium processor, and was also available for later Apollo/Domain systems.
