distributionofstoragemanagementandrecovery
模拟段式存储管理的分配与回收,能够输入给定的内存大小,进程的个数,每个进程的段数及段大小;当某进程提出申请空间的大小后,显示能否满足申请,以及为该进程分配资源后有关内存空间使用的情况。
(Analog-stage distribution of storage management and recovery, be able to enter a given memory size, number of processes, each process segment number and segment size when a space the size of the application process, the show can meet the application, as well as the The process, after the allocation of resources relating to the use of memory space.)

Storage_Simulator0001
在采用多道程序设计的系统中,往往有若干个进程同时处于就绪状态。当就绪进程个数大于处理机数时,就必须依照某种策略来决定哪些进程优先占用处理机。本实验模拟在单处理机情况下的处理机调度,帮助学生加深了解处理机调度的工作。
二、实验类型
设计型。
三、预习内容
预习课本处理机调度有关内容,包括进程占用处理机的策略方法。
四、实验要求与提示
设计进程调度算法,进程数不定;包含几种调度算法,并加以实现;输出进程的调度过程——进程的状态、链表等。要求使用优先权法和轮转法模拟进程调度过程。
【提示】:简化假设
1) 进程为计算型的(无I/O)
2) 进程状态:ready、running、finish
3) 进程需要的CPU时间以时间片为单位确定
【提示】:算法描述
1) 优先权法——动态优先权,当前运行进程用完时间片后,其优先权减去一个常数。
2) 轮转法

1.虚拟存储器的引入
局部性原理:程序在执行时在一较短时间内仅限于某个部分;相应的,它所访问的存储空间也局限于某个区域,它主要表现在以下两个方面:时间局限性和空间局限性。
2.虚拟存储器的定义
虚拟存储器是只具有请求调入功能和置换功能,能从逻辑上对内存容量进行扩充的一种存储器系统
(1. The introduction of virtual memory locality principle: program execution in a relatively short period of time limited to a particular part of it Accordingly, it has access to the storage space is also limited to a particular region, it is mainly manifested in the following two aspects: the time limitations and space limitations. 2. The definition of virtual memory Virtual memory is just a request for redeployment of functions and displacement functions, from the logical to expand the memory capacity of a memory system)
