基于PCI的ARINC429总线接口卡设计

摘要

为了实现计算机与使用ARINC429总线的航空机载设备进行数据通信,设计了基于PCI总线的ARINC429总线接口卡.上位机应用软件使用LabVIEW编写,下位机程序使用硬件描述语言Verilog编写.PCI接口芯片采用CH365,用FPGA内部嵌入的RAM实现双口RAM功能.经过实际测试,设计的板卡达到预期设计要求.系统操作界面友好、结构简单、工作稳定可靠,具有很好的应用前景.%In order to achieve data communications between computer and airborne equipment using ARINC429 bus, an ARINC429 bus interface card based on PCI is designed. Application software of host is written in Lab-WIEW and programs of slave are written in Yerilog that is a hardware description language. Dual-port RAM is realized by embedded RAM of the FPGA and using CH365 as the PCI interface chip. Expectations are implemented after actual tests. This system has a great application value for its user, which has friendly interface, simple structure and stability.
