操作系统课程设计《页面置换算法》,内含设计文档。
设计要求为:作业共有320条指令,即它的地址空间为32页,目前它的所有页都还未调入内存。再模拟过程中,如果所访问的指令已在内存,则显示其物理地址,并转下一条指令。如果所访问的指令还未装入内存,则发生缺页,此时需要记录缺页的次数,并将相应页调入内存。如果4个内存块均已装入该作业,则需要进行页面置换,最后显示其物理地址,并转向下一条指令。在所有320条指令执行完毕后,请计算并显示作业运行过程中发生的缺页率。
实现方法为:最佳置换算法(OPT)、先进先出(FIFO)算法和最近最久未使用(LRU)算法。-err

A user
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

动态分区存储管理方式的主存分配回收。存储管理中动态分区的管理方式,编写程序完成动态分区存储管理方式的主存分配回收的实现。实验具体包括:首先确定主存空间分配表;然后采用最优适应算法完成主存空间的分配,完成主存空间的回收;最后编写主函数对所作工作进程测试。存分配时查找空闲区进行分配,然后填写已分配区表,主要操作在空闲区-dynamic storage management through the distribution of the main deposit recovery. Dynamic Storage Management Division"s management style and preparation procedures are completed through dynamic storage management of main memory allocated to achieve recovery. Experiments including : first to identify the main deposit space allocation table; Then using the optimal algorithm to adapt to the completion of main memory space allocated main memory space complete recovery; Final preparation of the main function of the work done by the process of testing. When you deposit allocated for distribution free zone, and then fill in forms have been allocated to the district, mainly operating in the district idle
