摘　　要：针对目前常用ARINC429总线需要采用429专用接口芯片加控制器,并且存在体积大,协议速率固定的缺陷,设计了现场可编程门阵列(FPGA)取代429专用接口芯片的ARINC429总线。该设计将ARINC429总线协议写入到FPGA中,省去了专用接口芯片,通过对软件的修改可实现自定义协议及速率的改变。仿真与实测结果表明,该设计方案原理正确,满足设计要求,可以灵活地应用于ARINC429总线设计中。To break through the limitations of the specialized interface controller for traditional ARINC429 data bus,such as large volume and fixed data rate,a new implantation method based on Field Programmable Gate Array （FPGA） was put forward.With the application of FPGA in ARINC429 data bus,the protocol and data rate is enabled to have better flexibly by modifying the software.The conclusion was proved by the simulation and experiment with design requirements satisfied.Thus the method can be applied to ARINC429 designs.
