提高时钟置换算法的性能

时钟置换算法是一种常见的虚拟内存页面置换算法：增加修改位标志原理：在基本的时钟置换算法基础上，为每个页面增加一个修改位标志。当页面被修改时，将其修改位设置为1；否则为0。在进行页面置换时，优先选择使用位和修改位都为0的页面进行置换，因为这样的页面既未被最近使用，也未被修改ÿ...

时钟置换算法

时钟置换算法（Clock Page Replacement Algorithm），也称为最近未用置换算法（Not Recently Used，NRU），是一种在虚拟内存管理中用于页面置换的常见算法。数据结构与基本原理环形链表：时钟置换算法将内存中的所有页面组织成一个环形链表...
