摘要
设计的PCI插卡,实现了基于微机PCI总线的ARINC429接口.该卡通过一片DSP实现了数据自主收发的管理能力,减轻了微机CPU的负载,节约了微机资源.通过该智能卡,微机可与使用ARINC429总线的机载电子设备建立连接,从而可使用微机在地面对机载电子设备进行自动测试.
The ARINC429 interface card has been implemented basing on PCI local bus. A DSP is used to manage the receiving and sending data of the interface, and the PC＇s CPU load is abated. The card can be used to construct the connection between the PC and the aircraft built-in equipment, and the equipment is able to be tested automatically through a PC on the ground.
