Alpha (original name Alpha AXP) is a 64-bit reduced instruction set computer (RISC) instruction set architecture (ISA) developed by Digital Equipment Corporation (DEC). Alpha was designed to replace 32-bit VAX complex instruction set computers (CISC) and to be a highly competitive RISC processor for Unix workstations and similar markets.

Aug 7, 2017 · The Alpha AXP follows in the traditional RISC philosophy of having a relatively small and uniform instruction set. The first Alpha AXP chip was dual-issue, and it eventually reached quad-issue. ( There was an eight-issue processor under development when the Alpha AXP project was cancelled.)

The Alpha 21064 is a microprocessor developed and fabricated by Digital Equipment Corporation that implemented the Alpha (introduced as the Alpha AXP) instruction set architecture (ISA). It was introduced as the DECchip 21064 before it was renamed in 1994.

DEC Alpha は、 Alpha AXP としても知られ、 ディジタル・イクイップメント・コーポレーション (DEC) の 64ビット RISC 命令セットアーキテクチャ (ISA) であり、 32ビット VAX CISC ISA とその実装を置換すべく設計された。 AlphaはDECが マイクロプロセッサ として実装し 生産 した。 Alphaマイクロプロセッサは特にDECの ワークステーション や サーバ に使用され、ミッドレンジ以上のあらゆるコンピュータで採用された。 サードパーティもAlphaを使ったシ …

Aug 23, 2017 · The Alpha AXP is natively a 64-bit processor, but Windows NT for Alpha AXP treated it as a 32-bit processor. How is that possible?

The Alpha processor (originally known as Alpha AXP) is a 64-bit RISC (Reduced Instruction Set Computer) architecture developed by Digital Equipment Corporation (DEC). It was developed to replace the 32-bit VAX architecture and its Complex Instruction Set Computer (CISC) model.

Aug 14, 2017 · On the Alpha AXP, it is absolutely essential that you accurately declare the fact that a pointer may point to misaligned data. If you forget, then depending on the size of the data you are accessing and the precise nature of the misalignment, you might get away with it, or you might crash, or (worst case) you will proceed with incorrect data.

Alpha, originally known as Alpha AXP, is a 64-bit Reduced Instruction Set Computer (RISC) instruction set architecture (ISA) developed by Digital Equipment Corporation (DEC), designed to replace the 32-bit VAX Complex Instruction Set Computer (CISC) ISA and its implementations.

The DEC Alpha AXP architecture has a fascinating computing history. It was known as the legacy powerhouse specially designed for data-intensive applications. Despite many challenges, it has dominated the market for a very long time.

The DEC Alpha, also known as the Alpha AXP, is a 64-bit RISC microprocessor originally developed and fabricated by Digital Equipment Corp (DEC). Designed to power successors to the VAX line of computers, it was used in a variety of DEC workstations and servers, eventually forming the basis for almost all of their entire mid-to-upper-scale lineup.
