摘要
本文提出了一种基于改进的LRU替换策略划分最后一级共享Cache的算法,隔离了线程间的数据冲突,实现了改进的Cache替换策略,通过划分最后一级共享Cache也减少了访存延迟,提高了系统吞吐率.
There is some concern about how to partition the last shared cache to decrease the bad influence of resource competition and the rate of miss.This paper propose a method of partitioning the last shared cache using the modified LRU algorithm.It can eliminate the resource competition,decrease the memory latency,improve the replacement policy and improve system throughout.
