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).

DEC Alpha AXP 21064 Microprocessor DEC Alpha，也称为 Alpha AXP，是由 迪吉多公司 （DEC）開發製造的 64位 RISC 指令集架構 微处理器，并用于DEC自己的 工作站 和 服务器 中。

The Alpha AXP 64-b architecture, which forms the basis for a series of high-performance computer systems, is described. The implementation of this architecture in the 21064 microprocessor is discussed. This 1.4-cm*1.7-cm CMOS chip incorporates 1.68 million transistors using a 0.75- mu m, three-metal process.

2025年3月10日 · 21064 is a 64-bit superscalar microprocessor developed by Digital Equipment Corporation (DEC) in 1990s, and based on Alpha AXP architecture. The Alpha architecture was announced in February 1992, and the first 21064 processors, running at frequencies 150 MHz and higher, were launched at COMDEX show in November 1992.

The Alpha 21064A microprocessor is a 0.5-µm, CMOS-based, superscalar, super-pipelined processor using dual instruction issue and frequencies of either 200, 233, 275, or 300 MHz. The Alpha architecture is a 64-bit RISC architecture designed with emphasis on speed, multiple instruction issue, multiple processors, and multiple operating systems.

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. The 21064 is also known by its code name, EV4.

The Alpha AXP architecture and 21064 processor - IEEE Micro

The first implementation of the Alpha AXP architecture is the world's fastest single-chip microprocessor. The DECchip 21064 runs multiple operating systems and runs native-compiled programs that were translated from the VAX and MIPS architectures.
