主存空间的分配与回收的实验报告.根据可变分区的主存分配思想，首先设计记录主存使用情况的数据表格，用来记录空闲区和作业占用的区域，即“已分配区表”和“空闲区表”。然后在数据表格上进行主存的分配，其主存分配算法采用最优适应算法，即按作业要求挑选一个能满足作业要求的最小空闲区分配，具体实现时，把空闲区按长度以递增方式登记在空闲表中，分配时顺序查找空闲表，-Main memory space allocation and recovery of experimental reports. According to the variable partition of main memory allocation of thinking, first of all design records the use of main memory data tables used to record operating free zones and occupied the region, that is,　have been allocated to District Table　and　free zone table.　 And then in the data tables on the distribution of main memory, and its main memory allocation algorithm uses the optimal adaptation algorithm, that is, according to the selection of operational requirements to meet the operational requirements of a minimum free area distribution, when the concrete realization of the free zone by the length of ascending registered in the free form, the allocation order to find free sheet,
