主机与存储器之间的缓存专利技术分析

Cache Technology Analysis between Host and Memory

缓存处于主机和存储器之间,是快速、小型的具有存储功能的部件,它保存存储器中部分数据的拷贝,其容量不大,当主机频繁访问一小部分存储器中的数据时,缓存就显得意义较大,然而为了高速处理大量的数据,对存储器的存取速度和容量要求较高,因此,如何使主机与存储器之间匹配,同时不增加系统成本是研究的热点,本文介绍了缓存的基本概念,并结合现有的国内外专利,分析了当前缓存技术的发展状况及发展方向。

Cache is a fast and small storage component with storage function, locating between host and memory. Itsaves some data of the memory with little capacity. When the host frequently accesses to a small number of data inthe memory, the cache seems to be significant. But in order to process large number of data with high speed, there isa high requirement on the speed and capacity of the memory. Therefore, how to make the host match with the memorywithout increasing the system costis a hot research. This paper introduces the basic concept of the cache, and ana-lyzed the development situation and direction of current catch technology combining with the existing patent in Chinaand abroad.
