从程序员的角度看计算机操作系统~ 很不错的书 大家都加油了(Computer Systems--A Programmer s Perspective)

ThreadX的中文文档,提供了ThreadX实时内核的详细信息.(ThreadX the Chinese documents, provided the ThreadX real-time kernel details.)

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.)

操作系统文件管理实验：利用交互式命令实现树型目录结构和文件管理,同时利用位示图表示外存的分配情况，新建文件时分配必要的空间，模拟文件分配表记录文件在外存上的存储方式。了解系统对文件的操作。 在文件中保存目录内容，创建文件或子目录可以用命令行命令：MD、CD、RD、MK（创建文件）、DEL（删除文件）和DIR(Operating system file management experiment: the use of interactive command tree directory structure and file management, while taking advantage of the bit map indicates the distribution of the external memory, and allocate the necessary space when a new file is created, the simulation file allocation table log file is stored in the external memory way. Understanding of the system operation on the file. Save the contents of a directory in the file, create a file or subdirectory can use the command-line command: MD, CD, RD, MK (create a file), DEL (delete files) and DIR)

详细的介绍了Nucleus的使用方法 Nucleus PLUS嵌入式操作系统是目前最受欢迎的操作系统Nucleus PLUS 是为实时嵌入式应用而设计的一个抢先式多任务操作系统内核，其95％的代码是用ANSIC写成的，因此非常便于移植并能够支持大多数类型的处理器。(rtos of Nucleus)

弹出框口，精选ios编程学习源码，很好的参考资料。(Pop up box, select learning IOS programming source code, a good reference.)
