AMD K5体系结构分析

本文重点介绍了Ｋ５体系结构设计的两个重要特点：（１）如何将Ｘ８６这样的ＣＩＳＣ指令转化为类似于ＲＩＳＣ指令的ＲＯＰ；（２）Ｋ５的流水线的动态调度技术，即它如何利用保留站、缓冲池（ＲＯＢ）去检测指令间的数据依赖关系并保证程序执行语义的正确性。最后，我们对这些技术作了进一步讨论，看如何利用它们，以解决象ＶＬＩＷ这样的体系结构设计中所面临的软件兼容性等问题。

The Analysis of the AMD K5 Architecture

In this paper, we illustrate two important aspects during the design phase of the AMD-K5 architecture: 1)how to convert CISC-like instruction such as X86 into R0P ;2)the dynamic pipeline scheduling technology, that is, how to check the data dependency between instructions and gurantee the validity of programs. At last, by applying the design methodology of AMD-K5, we solve the problem of compatibility between VLIW-like architecture and CISC-like arcbitecture.
