摘　　要：以太网是构建分布式控制系统的一种理想通信平台.介绍了一种嵌入式系统的快速以太网接口方案,该方案采用适于控制的TMS320F2812DSP作为主控芯片,采用SMSC公司的LAN91C113I作为以太网接口芯片,具有接口简单方便易于实现的优点,为在分布式控制系统当中应用以太网通信技术提供了一种解决方法.本文详细讨论了LAN91C113I与TMS320F2812的硬件连接及基于DSP/BIOS的软件程序设计。Ethernet is an ideal platform for constructing distributed control system. A scheme of embedded system with fast Ethernet interface was developed, in which TMS320F2812 DSP was used as master chip, and LAN91C113I of SMSC Company was used as Ethernet interface chip. The interface of two chips was simple and easy to connect. It takes a method for distributed control system to use Ethernet technique,The hardware connection and the design of software program based on DSP/BIOS （running in TMS320 F2812 DSP） were particularly discussed.
