【摘要】 长期以来，ＭＩＰＳ一直被视为衡量计算机运算速度的主要性能指标之一。近年来，由于计算机结构的变化，使人们开始意识到以ＭＩＰＳ衡量计算机的运算速度存在着问题。但，迄今为止，人们对这一问题还没有完全认识清楚，还在以不同的方式使用着ＭＩＰＳ。本文从ＭＩＰＳ的定义出发，结合实例，全面地分析了以ＭＩＰＳ值度量计算机或比较不同的计算机的运算速度所存在的问题以及可能导致的错误结论。进一步地，本文还讨论了在一定的限制条件下使用ＭＩＰＳ的问题。更多还原

【Abstract】 The MIPS has been used as one of the popular computer performance indices for many years. Recently, since the development of computer architecture, some problems in using MIPS to evaluate and compare the performance of computers are discovered. But, so far, the problems of using the MIPS are not recognized thoroughly, and the MIPS index is still used in the field of computer performance evaluation without any restriction. From the definitions of the MIPS, the paper comprehensively analyses the problems in using the MIPS to evaluate and compare the performance. of computers. Furthermore, the paper discusses the application of the MIPS with certain restrictions.更多还原
