摘　　要：介绍目前PCI总线接口的常用实现方法及其优缺点,提出了一种利用X ilinx公司的PCI软核来实现多处理机高速通信中PCI接口的方法。该方法采用紧凑设计思想,通过把PCI软核、先进先出数据缓冲器(FIFO)和收发器结合起来完整实现PCI接口通信功能,并实现在一个FPGA芯片中。该PCI接口结构紧凑工作可靠,容易扩展应用在多处理机间的高速通信中。Some common methods for implementing PCI interface were introduced and their advantages and disadvantages were analysed. An implementing method of PCI interface in high-speed communication of muhiprocessor by using Xilinx PCI softcore was proposed. The PCI interface integrated PCI core, two asynchronous First-In First-Out（FIFO） data buffers and one transceiver, which was implemented in one FPGA. The PCI interface works reliably and easily and can be applied to muhiprocessor high-speed communication.
