摘要
航空电子全双工交换式以太网(AFDX)为航空电子设备之间的数据交换提供电气和协议标准。在研究AFDX虚拟链路层协议的基础上,提出一种基于现场可编程门阵列(FPGA)的AFDX虚拟链路层软件设计框架,给出基于FPGA的AFDX虚拟链路层发送模块和接收模块的设计与软件实现,应用结果表明,该设计框架可促进AFDX端系统的研发。
Avionics Full Duplex Switched Ethernet(AFDX) provides electrical and protocol standard for data exchange of aviation electronic equipment.Based on the brief introduction of AFDX protocol layer,this paper presents the AFDX Virtual Links(VL) layer software design framework based on Field Programmable Gate Array(FPGA),it gives the transmitter module and receiver module design of AFDX virtual link layer based on FPGA and software realization,results show that the design framework can promote development of AFDX end system.
