Cache Technic and Its Realization

对Ｃａｃｈｅ技术及其实现原理和应用进行讨论，重点介绍一种相联存贮器和快存的实现方法、地址结构和寻地操作。快存与主存以页为单位进行信息交换，当快存缺页时，提出以最少使用与先进先出相结合的替换策略和以矩阵排队电路为核心的缺页替换的实现原理。

This paper discusses the principle of technic realiztion and the application of the cache,focusing on the ways of realizing the content addressed memory and the fast memory as well as address structure and addressing operation. Fast mmemory and main memory transfer message with the unit of page and when there is a lack of page,the problem can be solved by the conversion strategy of combining the least recently used and first-in first-out and by means of the realization principle of the lack of page employing the logic queue circuit in the centry.
