基于FPGA的AFDX交换机内嵌ES处理模块的设计与实现

摘要

在航空电子全双工交换式以太网(AFDX,Avionics Full Duplex Switched Ethemet)的交换机中,内嵌终端节点系统(ES,end system)处理模块是连接外部终端与调度模块之间的关键部分.基于ARINC644规范第7部分,提出符合该规范的AFDX交换机内嵌ES处理模块的设计方案,采用软硬件协同设计方法对ES处理芯片进行设计与实现,并搭建平台进行测试验证,测试结果表明,所设计的ES处理模块能够达到ARINC664协议性能要求.%In AFDX (Avionics Full Duplex Switched Ethernet) switch,the embedded ES processing module is the key part to connect external terminal with scheduling module.Based on the seventh part of ARINC644 standardize,the design scheme of embedded AFDX switch ES processing module is put forward,which is designed mainly with the Hardware-Software Co-design method,and the platform is built to test and verify performance.The test results show that the designed ES processing module can meet the requirements of the ARINC664 protocol performance.
