操作系统内存调度例子

《自己动手写操作系统》一书里面的源码，个人认为对学习操作系统的朋友有点帮助。-"to write his own operating system," a book which the source code, personal view on learning the system a bit to help a friend.

1.实验目的： 模拟实现银行家算法，用银行家算法实现资源分配。 2.实验内容： 设计五个进程{P0，P1，P2，P3，P4}共享三类资源{A，B，C}的系统，{A，B，C}的资源数量分别为10，5，7。进程可动态地申请资源和释放资源，系统按各进程的申请动态地分配资源。要求程序具有显示和打印各进程的某一时刻的资源分配表和安全序列；显示和打印各进程依次要求申请的资源号以及为某进程分配资源后的有关资源数据。 3．程序设计和说明： 函数说明：anquan( )判断给某个进程请求后系统是否安全，anquan1（）判断当前系统是否安全。GetAll（）取得所有进程的的各个资源数据。详细说明请参见附录中的程序的文档说明。-1. The experiment : Simulation Algorithm bankers, bankers algorithm with the allocation of resources. 2. Experiment : Design 5 (process P0, P1, P2, P3, P4) (resource sharing three categories A, B, C), (A, B, C) amount of resources to 10,5,7. Dynamic process could apply to the resources and the release of resources, according to the system processes the application to dynamically allocate resources. Procedures required to display and print the process of a moment of the distribution of resources and safety sequence; Display and print the process followed for seeking resources, as well as a process of distribution of resources in the resource data. 3. Program design and description : F

微内核l4操作系统源码，对操作系统实现感兴趣的朋友可以看下，相信有 用-L4 microkernel operating system source code, the operating system to achieve interesting friends can look down, I believe useful to

页面的存储管理，几种不同的调渡算法，能更深刻的学习存储管理，是可运行的程序-pages of storage management, several different cross-algorithm, the more profound study storage management, operational procedures

设备管理主要包括设备的分配和回收、同时实现设备独立性。假定模拟系统中有A（3台）、B（2台）、C三种设备，采用安全分配方式。-Device Manager includes equipment distribution and recovery, while achieving device independence. Simulation system assumes that there are A (3 units), B (2 units), C three kinds of equipment, the introduction of safety distribution.
