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

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)

fptree
FP-growth算法的改进C++程序,具有较好的扩展性和应用性,本程序改成用行读取,然后在内存中解析。更有效的方式是采用块读取方式(本人在以前项目中验证过,速度大为提高。)(FP-growth algorithm C++ Procedures, have good scalability and application, the procedure changed to use line to read, and then resolve in memory. More effective approach is the use of block-read mode (I tested before the project, speed greatly improved.))
