The Alpha AXP architecture and 21064 processor

摘要

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. Performance measurement results for a variety of commonly used benchmarks under both OpenVMS AXP V1 and DEC OSF/1 V1.2 are presented.
