page fault

In this paper, we discuss the question of the page fault in a demand_paging system, and get a correct method to count the number of the page fault and the page fault rate.

为了解决关于请求分页系统下的缺页问题,通过对请求分页系统理论的深入研究,提出了对缺页次数和缺页率正确计算方法。

This paper mainly discusses a assumption of account page faults,which transformation from LRU and LFU elimination algorithm.

本文主要讨论一种从LRU与LFU淘汰算法中变形得到的一种求缺页中断的设想。

But in some cases, LRU algorithm causes many page faults, so improving LRU page replacement algorithm can reduce page faults, and therefore improve the performance of the system.

但LRU算法在某些情况下会产生较多的缺页失败,改进LRU算法,降低缺页失败次数,可以有效地提高系统性能。
