摘　　要：目前的总线卡大多数是基于PCI总线桥和专用处理芯片器来实现。为了在PCI总线卡上构建定制的高级应用,需要利用嵌入式CPU和操作系统。本文研究了通过PCI桥连接的双CPU环境特点,给出了通信设计要点。在此基础上研究了典型PCI桥配置和使用,最后给出了一个基于这些研究成果的安全网卡实例。Most of the PCI bus cards are implemented based on PCI bus bridge and special micro-processor chip to fulfill specific requirements. For advanced application with PCI bus cards, embedded CPU and OS are used. Environment characteristics of dual CPUs on PCI bridge were researched, and key points about communication design were summarized. The configuration and usage of typical PCI bridge were studied, and an example of security network interface card based on our research was introduced.
