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.)

实现多通道ADC采集，通过图形界面显示，通过操作DDS信号发生器实现扫频，将天线阻抗信息现实吧到屏幕(Multi-channel ADC acquisition, through the graphical interface display, through the operation of DDS signal generator to achieve frequency sweep, the antenna impedance information to the screen reality)

有界缓冲区内设有20个存储单元，放入/取出的数据项设定为1~20这20个整型数。 要求： (1)每个生产者和消费者对有界缓冲区进行操作后，即时显示有界缓冲区的全部内容.当前指针位置和生产者/消费者线程的标识符 (2)生产者和消费者各有两个以上 (3)多个生产者或多个消费者之间须共享对缓冲区进行操作的函数代码。">

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.)

QNX操作系统下程序开发的详细说明指南，包括微内核架构分析、进线程开发介绍及进程间通讯等。(QNX operation system programmer s guide )

哲学家进餐的问题，用程序模拟实现，解释死锁的产生、解除以及预防(dining philosophers problem, simulation procedures, explained Deadlock in lifting and prevention)

这是我做的操作系统里面的银行家算法的源程序，发上来供大家参考。(caozuoxitongyinhangjiasuanfa)

操作系统实验-死锁避免算法，word文档，详细，全，可执行，自己写的，希望快点能在贵网站下载。。。(Operating System Experiment- Deadlock avoidance algorithm, word documents, detailed, full, enforceable, wrote it myself, hope quickly in your website. . .)

说明：  提供官方开源的uCOS-III嵌入式实时操作系统源程序，可用于嵌入式操作系统的二次开发。(Provides the official open source ucos-iii embedded real-time operating system source program, can be used for embedded operating system secondary development.)
