线程同步机制。
互斥器的功能和临界区域很相似。区别是:Mutex所花费的时间比Critical Section多的多,但是Mutex是核心对象(Event、Semaphore也是),可以跨进程使用,而且等待一个被锁住的Mutex可以设定TIMEOUT,不会像Critical Section那样无法得知临界区域的情况,而一直死等。-Thread synchronization mechanism. Mutex" s function and the critical region is very similar. The difference is: Mutex spent more time than the multi-Critical Section, but the Mutex is the core object (Event, Semaphore is), you can cross-process use, and has been locked waiting for a Mutex can be set to TIMEOUT, not as Critical Section did not know the critical situation in the region, for so long and so die.

模拟一个页式虚拟存储系统,用FIFO和LRU置换算法,计算所发生的缺页次数。
1、模拟一个页式虚拟存储系统,用FIFO和LRU置换算法,计算所发生的缺页次数。每个进程在内存占有3页数据区,刚开始时数据区为空。有以下访问数据页序列:5 0 1 0 2 0 1 4 0 2 5 1 2 3 5 (测试数据)请分别模拟2、实现过程:1) 内存分配:给进程分配一定的物理块数,由用户输入物理块数,用数组元素模拟物理块。2) 由文件读入页面访问序列,用数组保存。3) 将要访问的页面依次调入内存,分配到物理块中,形成页框表。其表项号即物理块号(数组元素下标),将页号放入数组相应位置。 请点击左侧文件开始预览 !预览只提供20%的代码片段,完整代码需下载后查看 加载中 侵权举报
