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: |

Description: 2.设计一个虚拟存储区和内存工作区，并使用下述算法计算访问命中率。
1) 最佳置换算法（Optimal）
2) 先进先出法（Fisrt In First Out）
3) 最近最久未使用（Least Recently Used）
4) 最不经常使用法（Least Frequently Used）
5) 最近未使用法（No Used Recently）
其中，命中率＝１－页面失效次数／页地址流长度。
试对上述算法的性能加以较各：页面个数和命中率间的关系；同样情况下的命中率比较。
-2. To design a virtual memory storage area and work area, and access using the following algorithm to calculate the hit rate. 1) The best replacement algorithm (Optimal) 2) FIFO (Fisrt In First Out) 3) most recently from lack of use (Least Recently Used) 4) the least frequently used method (Least Frequently Used) 5) does not use a recently (No Used Recently) where hit rate = 1- invalid page number/page address stream length. Test the performance of the algorithms to be compared with each: the page number and the relationship between hit rate the same hit rate in case of comparison. Platform: |
