关于操作系统课程的主存空间的分配与回收

采用可变分区存储管理，采用空闲分区表（链）进行。设计一个空闲分区表（链），空闲分区通过空闲分区链来管理；在进行内存分配时，系统优先使用空闲区低端的空间。

设计一个某时刻主存空间占用情况表，作为主存当前使用基础。初始化空闲区和已分配区说明表的值。自己设计一个作业申请队列以及作业完成后的释放顺序，实现主存的分配和回收。把空闲区分区表的变化情况以及各作业的申请、释放情况显示、打印出来。

算法，用MFC环境实现。

-Distribution and recovery of the variable partition of main memory space on the course of the operating system storage management, the use of the idle partition table (chain). Design an idle partition table (chain), idle partitions to manage through the idle partition chain　during memory allocation, priority use of the lower end of the free zone of space. A certain time of the design of main memory space occupancy of the table as a main memory currently in use basis. Initialize the free zone and have been assigned areas to illustrate the value of the table. Design a job request queue and the job is completed after the release order, the main memory allocation and recovery. Idle partition table changes, as well as job applicants, the release shows, print it out. Algorithm, using MFC environment.
