Description: 关于操作系统的内存管理，如何节省利用容量不大的内存为最多的进程提供资源，一直是研究的重要方向。而内存的虚拟存储管理，是现在最通用，最成功的方式—— 在内存有限的情况下，扩展一部分外存作为虚拟内存，真正的内存只存储当前运行时所用得到信息。这无疑极大地扩充了内存的功能，极大地提高了计算机的并发度。虚拟页式存储管理，则是将进程所需空间划分为多个页面，内存中只存放当前所需页面，其余页面放入外存的管理方式。 -About operating system memory management, how to save use of memory capacity is the most process to provide resources, has been one of the important research direction. And the virtual memory storage management, is now the most versatile, the most successful way-in memory is limited, as part of expansion CRT virtual memory, the real memory storage used when the current operation only get information. This undoubtedly greatly expanded memory function, which has greatly enhanced the computer concurrent degree. Virtual page type storage management, is needed for the process is divided into many pages space, memory storage needed only the current page, the rest of the page into the management method of CRT.

Description: 编写一个程序，模拟一个页式虚拟存储管理系统。（不考虑地址转换）
其中，由系统随机产生进程；
进程大小、进程到达次序、时间、进程执行轨迹（页面访问顺序）也随机生成，但进程之间必须有并发存在，进程执行时间需有限，进程调度采用时间片轮转算法（以页面模拟）；
物理块分配策略采取固定分配局部置换；
分配算法采用按比例分配算法；
调页采用请求调页方式；
置换采用LRU算法；
驻留集大小可调，观察驻留集大小对缺页率的影响。-Write a program that simulates a paged virtual memory management system. (Without regard to the address conversion) wherein the system generates a random process process size, the process order of arrival, time, the process execution trace (page access sequence) is randomly generated, but there must exist between concurrent processes, the process time required to perform a limited process scheduling algorithm using time slice (page-analog) physical block allocation strategy to take a fixed allocation of partial replacement allocation algorithm using a pro rata allocation algorithm paging using demand paging mode replacement using LRU algorithm resident set size adjustable observe the resident set size affect the rate of missing pages.

Description: 页式存储管理模拟
描述：根据虚地址中的用户号和虚页号同时查快表和慢表，当快表中存在此虚页号，就读出实页号，并计算主存实地址。如果所需页面没有在快表当中，等待慢表的访问结果，如果慢表中也不存在（装入位=0）怎产生缺页中断，调入所需页面，如果主存有空闲页面，则直接调入，否则使用LRU替换算法淘汰主存中某一页，调入新的页面，并更新快表。-Page storage management simulation Description: while the investigation fast and slow table based on the virtual table address user number and the virtual page number, fast table when this virtual page number exists, attending a real page numbers, and calculate the real address of main memory.
