摘要
基于ｘ８６指令系统之上，简要介绍高性能奔腾（ＰｅｎｔｉｕｍＰｒｏ）的片上结构，论述其ＣＩＳＣ与ＲＩＳＣ相结合的超标量、超流水线的结构特点，并描述其支持“乱序执行”的工作过程。
Based on the x86 instruction system,this paper gives a brief description of the chip structure of Pentium Pro,expounds the structural characteristics of the superscalar and superpipeline of the combination of CISC with RISC and describes the action process of its supporting 'out of order execution'.
