Linux 操作系统提供进程间通信（IPC）机制，用来保证正在执行的进程在内核的协调下能够 共享资源、同步以及交换数据等。Linux 支持大量进程间通信机制，包括信号、等待队列、管道 以及Unix 系统V 中提供的进程间通信机制，如消息队列、信号量和共享内存。-Linux operating system to provide inter-process communication (IPC) mechanism used to ensure that the process is being implemented in coordination with the core to share resources, synchronization and exchange information. Linux support a large number of inter-process communication mechanisms, including signal and wait for the queue, pipeline and the Unix System V to provide inter-process communication mechanisms, such as message queue, the signal volume and shared memory.

这是一个利用8254芯片为核心的嵌入式电子乐器的程序，通过输入qwertyu/asdfghj/zxcvbnm实现音调1234567的发生，同时还预先存放了一首歌--little star。输入p字符进行播放。

主要介绍一种基于Philips公司的MF RC500的射频识别读写器的设计：首先介绍系统的组成以及MF RC500的特性，接着给出天线的设计规范，最后给出MCU 89C52与MF RC500的接口原理图、对Mifare卡操作流程以及及读卡的程序。-Mainly based on the introduction of a Philips company MF RC500 RFID reader design: First of all system components as well as the introduction MF RC500 features, and then given antenna design specifications, and finally gives MCU 89C52 interface with the principle of MF RC500 diagram, the operation flow of the Mifare card and the card reader as well as procedures.
