“Cache-主存”和“主存-辅存”存储层次的对比分析

Contrasting Analysis of Memory Levels of "Cache-Main Memory" and "Main Memory-Auxiliary Memory"

本文对"Cache-主存"和"主存-辅存"这两种存储层次依据的原理和基本思想、引入的目的、硬件组成、失效开销、映像规则、查找方法、替换算法、写策略等多个方面进行了对比分析。以加深对存储层次的理解,提高对层次结构设计思想的认识。

The paper contrasts and analyzes the aspects of ＂main memory-auxiliary memory＂,such as their principles and basic theories,the purpose of introducing them,the composition of the hardware,mess penalty,alternative algorithm,search methods,and so on.Thus the understanding of the memory levels and the principles behind them canbe deepened.
