对传统页面置换算法的分析与研究

The Analysis and Research for Traditional Page Replacement Algorithm

随着虚拟存储技术在操作系统中的应用,大大提高了操作系统的性能,其中页面置换算法是虚拟存储管理的重要组成部分,页面置换算法的优劣将直接影响系统的整体性能。随着大量有着不同读写速度的外存设备共存于系统中,单一置换算法同样影响着系统的整体性能。

With the virtual storage technology applications in the operating system,greatly improved the performance of the operating system.And virtual memory page replacement algorithm is an important part of management.Page replacement algorithm will directly affect the merits of the overall system performance.With the large number of read and write speeds with different external memory devices co-exist in the system,a single replacement algorithm also affects the overall system performance.
