2024年11月11日 · OpenPA is an independent technical resource on HP 9000 and PA-RISC computers and operating systems. Online since 1999, there are more than 140 OpenPA articles on PA-RISC, a technical computer architecture developed by HP in the 1980s and 1990s:

PA-RISC （ぴーえーりすく）は、 ヒューレット・パッカード 社 (HP) の Systems & VLSI Technology Operation が開発した マイクロプロセッサ アーキテクチャ である。 その名前にも含まれているように RISC アーキテクチャの実装であり、PAは Precision Architecture （精密なアーキテクチャ）の略である。 また、 HP/PA つまり Hewlett Packard Precision Architecture と呼ばれることもある。 1986年2月26日、PA-RISCの最初の実装であるTS1を採用した HP …

The PA-RISC project provides a native port of Linux to the PA-RISC architecture. The port was merged into linux-2.6 and linux-3.x mainstream kernel tree. PA-RISC Linux Project History tells how the project got started and the first steps.

With QEMU, a full HP Visualize B160L and C3700 workstation can be emulated to run PA-RISC operating systems like HP-UX Unix and compatible applications. Systems support QEMU supports emulating two types of PA-RISC workstations, both 32-bit and 64-bit, with necessary devices and I/O.

2000年2月17日 · Summary of PA-RISC architecture and implementations up to PA-8600 and features of the PA 8700 implementation. Enabling Optimizations to Achieve Higher Performance on the HP PA-RISC Architecture. Discusses how to measure CPU perf, what impacts it, and HP compiler options. Configurability of the PA 7300LC.

HP 9000 PA-RISC computers are based on HP Precision Architecture, a conservative HP RISC design from the 1980s and 1990s for Unix servers and workstations. HP’s own PA-RISC processors from the early 32-bit TS-1, based on TTL, to …

Precision Architecture RISC (PA-RISC) or Hewlett Packard Precision Architecture (HP/PA or simply HPPA), is a general purpose computer instruction set architecture (ISA) developed by Hewlett-Packard from the 1980s until the 2000s.

PA-RISC machines need a firmware (“PDC” = Processor Dependend Code), and QEMU comes with a precompiled firmware which is based on a fork of SeaBIOS. QEMU for PA-RISC has been developed by: Richard Henderson : QEMU CPU emulation, QEMU hardware drivers

PA-RISC Debugging. 1. Absolute addresses; 2. HPMCs; 3. Q bit fun; Register Usage for Linux/PA-RISC. General Registers as specified by ABI; Feature status on parisc architecture

The 800 Series was the first line of HP computers to employ HP's new Precision Architecture (PA) RISC (Reduced Instruction Set Computer) CPUs. The Model 840 was introduced in 1986. HP's RISC development program was code-named Spectrum.
