对基于目录的高速缓存一致性协议的改进

The Improvement of Directory-based Cache Coherence Protocol

在多处理嚣系统中,高速缓存的一致性协议是很重要的。一般有监听总线协议和基于目录的协议两种。而基于目录的 协议又可以分为三类,各有一些缺点。本文提出了一个基于目录的高速缓存一致性协议的改进方案。

It is important for Cache Coherence Protocol in Multiprocessor Systems. The protocol includes Snoopy Protocol and Directory-based Protocol. Directory-based Protocol have some disadvantages. The Improvement of Directory-based Cache Coherence Protocol is put forward in this paper.
