1、操作系统实 验 报 告课程名称操作系统实验课程编号实验项目名称物理存储器与进程逻辑地址空间的管理 学号年级2011姓名车红岫专业信息安全学生所在学院国家保密学院指导教师刘 刚实验室名称地点计算机基础第三实验室 21B284 哈尔滨工程大学计算机科学与技术学院第一讲 实验环境的使用一、实验概述1. 实验名称物理存储器与进程逻辑地址空间的管理 2. 实验目的l 通过查看物理存储器的使用情况，并练习分配和回收物理内存，从而掌握物理存储 器的管理方法。 l 通过查看进程逻辑地址空间的使用情况，并练习分配和回收虚拟内存，从而掌 握进程逻辑地址空间的管理方法。 3. 实验类型（验证、设计）验证+设计4.

2、实验内容3.1 准备实验 3.2 阅读控制台命令“pm”相关的源代码，并查看其执行的结果 3.3 分配物理页和释放物理页 3.4阅读控制台命令“vm”相关的源代码，并查看其执行的结果 3.5 在系统进程中分配虚拟页和释放虚拟页 3.6 在应用程序进程中分配虚拟页和释放虚拟页 3.6.1 要求 创建一个EOS应用程序，并编写代码完成下列功能： 1. 调用API函数VirtualAlloc，分配一个整型变量所需的空间，并使用一个整型变量的指针指向这个空间。 2. 修改整型变量的值为0xFFFFFFFF。在修改前输出整型变量的值，在修改后再输出整型变量的值。 3. 调用API函数Sleep，等待10

3、秒钟。 4. 调用API函数VirtualFree，释放之前分配的整型变量的空间。 5. 进入死循环，这样应用程序就不会结束。 3.6.2 测试方法 二、实验环境Os Lab ，C语言三、实验过程（每次实验不一定下面6条都写，根据实际情况定）1实验要求1，22尝试在调用MmAllocateVirtualMemory函数时将RegionSize参数的值设置为PAGE_SIZE+1或者PAGE_SIZE*2+1。观察“输出”窗口中转储的信息，并说明申请虚拟内存的大小与实际分配的大小之间的关系，以及分配的虚拟内存大小会对分配的虚拟地址产生什么样的影响。将“输出”窗口中转储的信息保存在文本中。3尝试在

4、调用MmAllocateVirtualMemory函数时将BaseAddress参数的值设置为已经被占用的虚拟内存，例如0xA，观察“输出”窗口中转储的信息。将“输出”窗口中转储的信息保存在文本文件中。 4尝试在调用MmAllocateVirtualMemory函数时将RegionSize参数的值设置为PAGE_SIZE*2，将BaseAddress参数的值设置为0xA，观察“输出”窗口中转储的信息，并说明申请虚拟内存的大小与实际分配的大小之间的关系，以及申请的虚拟地址会对分配的虚拟内存大小产生什么样的影响。将“输出”窗口中转储的信息保存在文本文件中。 5.修改代码后结果：6. 源程序并附上注
