操作系统试验！通过这个试验，你可以更加详细的了解的一些操作系统方面的知识！-Test operating system! Through this test, you can a more detailed understanding of some of the operating system of knowledge!

操作系统Clock算法的Java实现，包括三个文件： Node_Clock.java，作业封装类。Clock.java，实现Clock算法。Test.java，main。编的不太好，但是清楚明白，供大家借鉴。                                                             

WarmOS是一个用汇编编写的16位实模式操作系统，它包括了一些操作系统应该拥有的基本功能，支持COM格式文件的执行，提供了一些系统API以供程序员编写程序，并且从内核支持中文的显示。

这是个银行家算法看看哦-This is a look at the banker"s algorithm oh

linux内核，它非常适合用于学习操作系统的原理以及对相关操作系统的开发也有很好的借鉴作用-linux kernel, it is very suitable for learning the principles of operating systems, as well as the development of the relevant operating system also has a very good reference

已移植到TI OMAP1610处理器的Nucleus操作系统源码，并提供了一个Demo的应用程序。-have been transplanted to the TI OMAP1610 processor Nucleus operating system source code, and provide a Demo applications.

一个微型操作系统源码-a micro-source operating system

DOS - ç ，它的内核也是FreeDOS的内核。并在此基础上进行了一定的修改，使其更加实用。 FreeDOS的是项目设计 提供替代到MS - DOS，PC的DOS的和DR - DOS的自由 。-DOS-C started in 1988 as an experiment in writing device drivers in C for Microsoft s MS-DOS. Both block and character device drivers were written, along with special C data structures to match the MS-DOS request packet. It was then recognized that using the same techniques, an operating system could be written that would take advantage of the C language features and would require much less time to develop than the traditional assembly language techniques. Although UNIX had proven this earlier, it was not tried with a traditional pc operating system. At this time, a minimal operating system using the device drivers written earlier along with a new 8086 interrupt API was developed. It was called XDOS and proved to be a functional operating system. This new operating system was used to develop booting techniques and a C library SDK was dev

通过研究Linux的线程机制和信号量实现读者写者(Reader-Writer)问题并发控制。 1)写-写互斥：不能有两个写者同时进行写操作； 2）读-写互斥：不能同时有一个线程在读，而另一个线程在写； 3）读-读允许：可以有一个或多个读者在读； 4）读者优先的附加限制：如果读者申请进行读操作时已有另一个读者正在进行读操作，则该读者可直接开始读操作； 5）写者优先的附加限制：如果一个读者申请进行读操作时已有另一个写者在等待访问共享资源，则该读者必须等到没有写者处于等待状态后才能开始读操作。 -By studying the Linux thread mechanism and semaphores realize readers who write (Reader-Writer) the issue of concurrency control. 1) to write- write mutex: Can not write at the same time there are two write operations 2) read- write mutex: Can not have a thread at the same time in reading and writing another thread 3) Reading- Reading of permit: can have one or more readers read 4) the priority of additional restrictions readers: If the readers apply for a read operation, there was another reader being read, the reader can be directly started reading operation 5) to write additional priority Restrictions: If an application for a reader reading write operation has been in waiting for another visit to a shared resource, the read
