Digital's 21064 Microprocessor

This document introduces the Digital 21064, the first implementation of the 64-bit Alpha RISC architecture. It highlights the processor's industry-leading performance, achieving 300 MIPS and 150 MFLOPS at 150 MHz. Key features include a single-chip implementation using 0.75-micron CMOS technology, a super-scalar and super-pipelined design, and compatibility with both VAX and IEEE floating-point standards. The document also emphasizes the architecture's longevity, scalability for multiprocessor configurations, and the support for multiple operating systems like OSF/1 and VMS through binary translation and a flexible software library.
