摘　　要：基于FPGA的通信卡设计原理。通信卡实现了4路ISDNU接口、4路RS232串口、2路音频接口及1路PCI总线之间的通信,该卡以FPGA(现场可编程门阵列)和MPC860为核心进行设计,利用FPGA的可编程性灵活实现了各接口之间的数据通信。本文给出了系统的硬件构架,并对串口传输功能和数字交换网络功能的FPGA实现进行了分析。The design principle of communication card is introduced. This card, in which FPGA and MPC860 take a great part, realizes data communication in various interfaces, including 4 ISDN U ports, 2 audio-fidelities and 1 PCI bus by programming FPGA conveniently. The hardware frame of this card is given, the function of serial port transfer and digital switch net, implemented in FPGA, are analyzed.
