【摘要】 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。更多还原

【Abstract】 Embedded System is often selected by telecommunication manufacturers because of its high credibility,low volume and flexible configuration,it has been widely applied to development and integration of system .The embedded system includes hardware and software system development,also the interface between two systems.The methods of design and implement of the interface are very itch.The article introduces the classify of the architecture of the embedded system in brief,and particularly talks about the advantages and disadvantages of the different interface technologies. Finally,it emphasizes details of two sort of interface configuration with the practice.更多还原
