摘要
Cache即高速缓冲存储器,位于CPU与主存之间,是现代计算机不可缺少的组成部分,其性能的高低可直接影响计算机整体的工作效率。本文用软件模拟硬件的方法,依据Cache的基本工作原理,分析了Cache在不同工作策略下的命中率问题。
Cache locates between CPU and main memory, is an important com ponent of modern computer system and has a great influence over the work efficiency of the syste m. In this article, the basic principle of Cache is introduced, and the approach to the design and realization of the c ache simulation system is discussed in detail. At last the strategies to enhance the Cache hit rate are compar ed.
