对LRU页面置换算法的理论改进

Improvement thought of the LRU Page-Replacement Algorithms

在对内存进行虚拟管理时 ,页面置换算法的好坏直接影响着系统的性能 .现有的常用算法有四五种 ,文章对其中比较合理的算法——最近最少使用算法 ( LRU)进行理论上的改进 .

At the proceeding virtual management to the memory,the quality of the Page-Replacement Algorithms directly affects the function of the system. The type of the current and in common use reach four and five,of which Least Recently Used Algorithms (LRU) is a reasonable one comparatively.The improvement of LRU theoretically is discussed.
