2、掌握分区分配的一下三算法：首先适应算法、最佳适应算法和最坏适应算法
3、掌握动态分区分配的存储分配和存储回收的过程
二、设计要求
1、建立空闲分区表数据文件，该文件包括两个字段：空闲区的起始地址和长度；该文件有若干个记录，表示目前系统有多个空闲分区；
2、建立已分配分区表数据文件，该文件包括三个字段：已分配分区的起始地址、长度、作业名称；该文件有若干个记录，表示目前系统有多个作业；
3、程序启动时读两分区表数据文件，并在屏幕上显示内存的使用状态
3、接受用户的内存申请，格式：作业名、申请空间的大小
4、分别按照三种内存分配算法，选择一个空闲分区，分割，修改空闲分区表、填写已分配分区表；
5、接收作业结束信息，回收分配给作业的分区，必要时合并空闲分区，改写两个分区表；
6、在接受用户的内存申请时，当申请空间的大小大于目前任意一个空闲分区而小于若干个空闲分区的大小之和时，分配前进行碎片整理-1, designed to

Description: 存储器的分配与回收算法实现
采用最先适应法、最佳适应法、最坏适应法分配主存空间。当一个新作业要求装入主存时，必须查空闲区表，从中找出一个足够大的空闲区。若找到的空闲区大于作业需要量，这是应把它分成二部分，一部分为占用区，加一部分又成为一个空闲区。-Memory allocation and recovery algorithm
To adapt to using the first method, the best fit method, the worst fit method to allocate main memory space. When a new operational requirements into the main memory, you must check the free area table, to find a large enough free area. If you find a spare area is greater than the job requirements, this is it should be divided into two parts, one for the occupied area, plus a part of has become a free zone. Platform: |
