嵌入式系统由其高可靠性、体积小和配置灵活受到通信厂商的青睐，在当今的系统开发和集成中应用广泛。嵌入式系统的开发包括硬件系统的开发和软件系统的开发及两者间接口的开发，而在这两者的接口实现中可采用的技术及其实现方案非常丰富。文章简单介绍了嵌入式系统模型的划分，详细讨论了各种接口技术的优缺点。最后结合实践重点讨论了两种接口配置方案的实现细节。
Embedded systems are favored by communications vendors for their high reliability, small size and configuration flexibility, and are widely used in today’s system development and integration. The development of embedded system includes the development of hardware system and the development of software system as well as the development of the interface between the two. However, the technologies that can be used in the implementation of these two interfaces and their implementation schemes are very rich. The article briefly introduces the division of the embedded system model and discusses in detail the advantages and disadvantages of various interface technologies. At last, the implementation details of the two interface configuration schemes are discussed in detail.
