vc开发的关于操作系统的液面置换的模拟-vc development of the operating system on the surface of the simulation replacement

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

A user-space device driver can do many of the things that kernel drivers can t, such as perform a long-running computation, block while waiting for an event, or read files from the file system. Unlike kernel drivers, a user-space device driver can use other device drivers--that is, access the network, talk to a serial port, get interactive input from the user, pop up GUI windows, or read from disks. User-space drivers implemented using FUSD can be much easier to debug it is impossible for them to crash the machine, are easily traceable using tools such as gdb, and can be killed and restarted without rebooting even if they become corrupted. FUSD drivers don t have to be in C--Perl, Python, or any other language that knows how to read from and write to a file descriptor can work with FUSD. User-space drivers can be swapped out, whereas kernel drivers lock physical memory.-A user-space device driver can do many of the things that kernel drivers can t, such as perform a long-running comput
