摘　　要：通信系统是航电系统的重要组成部分,决定了控制室发出的指令能否快速、可靠地发送到功能执行模块。上个世纪广泛使用的ARINC429和ARINC629总线,由于传输速率限制,已经无法满足现代飞机的需求,因此,基于ARINC664标准的AFDX总线已经成为目前主流机型的选择。论文从硬件和软件两个方面介绍了如何基于FPGA芯片实现AFDX端系统的功能,实现AFDX数据与PCI数据的相互交换,并搭建了硬件平台、设计了软件代码,对端系统进行了性能测试。Communication systemis an important part of the avionics system,which determines whether the commands issued by the control roomcan be sent to the functional execution module quickly and reliably.ARINC 429 and ARINNC 629,widely used in the last century,can not meet the needs of modern aircraft because of the transmission rate limitation.Therefore,AFDX bus based on ARINC 664 standard has become the mainstreamchoice of aircraft.This paper introduces how to realize the function of AFDX terminal system based on FPGA chips from both hardware and software aspects,and realize the exchange of AFDX data and PCI data,and builds the hardware platform,designs the software code,and tests the performance of the system.
