1)设计一程序,由一个进程创建三个子进程,三个子进程一个是生产者进程,两个是消费者进程。
2)父子进程都使用父进程创建的共享存储区进行通信,由生产者进程将一个数组中的十个数值发送到由5个缓冲区组成的共享内存中。?
3)两个消费者进程轮流接收并输出这十个数值,同时将两个消费者进程读出的数值进行累加求各和。
4)考虑生产者进程生产的速度和消费者进程速度。(1) a program is designed to create three sub processes from one process, three sub processes is the producer process, and the two is the consumer process.
2) the father child process communicates with the shared storage area created by the parent process, and sends ten values in one array to the shared memory composed of 5 buffers by the producer process. L
3) the two consumer processes take turns to receive and output the ten values, and add values to each of the two consumer processes.
4) take into account the production speed of the producer process and the speed of the consumer process.)

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)

LRU
利用LRU算法仿真请求页面系统
1、设计内容:用高级语言编写和调试一个内存分配程序,加深对内存分配算法的理解。
2、设计要求:
1) 实现请求分页存储管理方式的页面置换算法:近期最久未使用算法(LRU)
2) 内存物理块数固定为3个,对多个作业采用可变分配全局置换的策略分配物理块
3) 作业数量与作业大小(0-9页)可在界面进行设置
4) 所有作业按RR算法进行调度,时间片长度为1秒
5) 可为每个作业随机产生引用的页面串,也可以人工输入引用的页面串,页面串长度50---100,要求必须包括作业所有的页面,可作为样例数据保存
6) 可读取样例数据(要求存放在外部文件中)进行作业数量、作业大小、页面串长度的初始化
7) 要求采用可视化界面,模拟内存分配和使用情况图,可在运行过程中随时暂停,查看当前内存物理块使用情况。
8) 每次全部作业运行结束后,要求打印出访问命中率
