摘要
阐述了虚拟存储中各类置换算法的基本思想和算法的实现,并比较了它们的优缺点,以及在同一置换算法中对该算法的几种不同分析理解方法,讨论了如何才能把缺页率保持在一个合理的水平上。
This paper elaborated the basic idea of all kinds of substitution algorithms in virtual storage and the realization of algorithm. It also compared the advantages and disadvantages of all kinds of substitution algorithms, and compared several different analysis and comprehension methods of one replcaement algorithm. This paper disscussed that how to keep the rate of page lack on a reasonable level.
