支持多种航电通信协议系统的设计

摘要

以FPGA为核心、HI-1575和SFP为接口设计了一个可以支持1553B、FC．AE、FC—AE-1553B三种航电通信协议的开发板，并基于此开发板搭建网络系统，完成相应协议下的通信工作。同时，网络上的数据可以通过开发板上的PCIE、Ethemet接口实时地传输至计算机，并完成数据测试。%Taking FPGA as a core, HI-1575 and SFP as interfaces, a development board which can support 3 kinds of avionics communication protocols like 1553B, FC-AE, FC-AE-1553B is designed, and network based on this board is established to accomplish communication work under corresponding protocol. Meanwhile, the data from Internet can be transmitted to the computer via PCIE, Ethernet interfaces on the development board in real time, and used to accomplish data test.
