摘要: 在页式虚拟存储系统中,较常用的页面置换算法有RG,NUR,LFU,OPT,FIFO,LRU,其中LRU算法是一种最通用的有效算法,最接近于理想状态.在实际应用中,LRN算法有多种实现方法,和其它几种页面置换算法相比较存在明显的优点.关键词:页面置换算法 LRU算法 缺页率 ...
Over the years many algorithms have been proposed for page replacement. Each algorithm attempts to minimize the page fault rate while incurring minimum overhead. , In this paper we discuses at the traditional algorithms such as LRU. Least Recently Used (LRU) page replacement algorithm is most ...
Although they outperform the traditional LRU policy in performance, they do not consider the access frequency of clean page, which will consequently result in poor I/O performance. In order to solve this problem, we present a new buffering algorithm in this paper, called CCF-LRU, which ...

Another problem with the Meade algorithm is that its LRU algorithm requires a significant amount of processing time, equal to the time for shifting out a word in the LRU array one bit at a time, each time a block or page must be replaced in the buffer. The block or page replacement tim...
