Description: 功能介绍：
l 输入进程P总共有的页面数，l 并输入系统已经在内存中分配的页面数。当所分配的页面数大于进程P的页面数时，l 则不l 需要进行页面调度工作。
l 由进程P的页面数目，l 程序随机生成一些访问内存的页面号，l 为简化程序，l 这些页面号的数目同l 进程P的进程数目一致（这个缺陷也有待改进）。
l 由用户选择FIFO算法还是LRU算法对进程P的页面访问内存分配的页面进行分配，l 并输出具体的页面访问过程。
原理介绍：
请求页式管理中的置换算法：置换算法在内存中没有空闲页面时调用。它的目的是选出一个被淘汰的页面。如果内存中有足够的空闲页面存放所调入的页，则不必使用置换算法。
先进先出算法FIFO：该算法总是选择在内存驻留时间最长的一页将其淘汰。其认为先调入内存的页不再被访问的可能性要比其他页大，因而选择最先调入内存的页换出。
最近最久没使用页面淘汰算法LRU-functional presentations : 1 P process imported a total of some pages. l and enter the system has been allocated in memory of a few pages.

Description: 改进型CLOCK 页面置换算法实现在进程运行过程中，若其要访问的页面不在内存而需要调入内存，但分配该进程的内存
空间已经用完时，为了保证该进程能继续执行，需要从内存中把该进程的一些页调入外存中
的对换区，但调出那个页面，可以采用不同的算法。-Improved CLOCK page replacement algorithm in the process of running the course, if its trying to access pages of memory need not be transferred to memory, but the distribution of the process had run out of memory space, in order to ensure that the process can continue execution from memory in the process of redeployment of a number of pages for Out-of-Core of the area, but out of that page, you can use different algorithms.

Description: 根据请求调页存储管理方式的相关原理，编程模拟实现一个请求调页存储管理系统，该系统的页面置换算法必须包括先进先出页面淘汰算法（FIFO）、最近最少使用LRU页面淘汰算法和最佳淘汰算法。同时系统可以随意设置当前分配给作业的物理块数。
系统运行时，任意输入一个页面访问序列，设定不同的页面置换算法和物理块数，输出其页面淘汰的情况，计算其缺页次数和页面置换次数。
系统结束后，要求比较同一个页面访问序列，在不同的页面置换算法和物理块数的情况下，其产生的缺页次数和页面置换次数，并分析其原因。
-Paging, on request of the related storage management principle, the realization of a programmable analog paging request storage management system, the system s page replacement algorithm must include the page-out algorithm FIFO (FIFO), least recently used LRU algorithm for page-out and the most Jia-out algorithm. At the same time, the current system settings can be allocated to the operation of the physical block number.
Run-time system, a page arbitrarily input sequence set different page replacement algorithms and a number of physical blocks, the output of the circumstances out of its pages to calculate the number of missing pages and the number of page replacement.
System after the request for comparison with the sequence of a page, the page in different physical block replacement algorithm and the number of cases, the resulting lack of page number and the number of page replacement, and to analyze its causes. Platform: |
