某专用429总线接口协议的FPGA实现

摘要

ARINC429是一种在航空电子系统领域被广泛应用的总线标准。针对空空导弹专用429总线,提出了一种内置控制核的通用化、模块化的429总线协议IP核设计方法,使其具有内部存储能力,以及通道数可裁减,波特率、中断请求时间和收发模式等可选择,移植性较强等特点。利用硬件语言VHDL,采用基于FPGA的硬件实现方法,有效地提高数据通信模块的处理能力和集成度,降低了研制成本,提高了研制效率。%ARINC429 has been used widely in the avionics system.This paper proposes a design concept of 429BUS IP core based on the architecture of communication chip by controlling embedded core and mass memory with FPGA technology for special 429BUS on air-to-air missile.And the core is all-purpose,modularized,automated and transplantable.Its channels,baud rate,interrupt time can be choosen.This paper adopts the VHDL hardware language,which can effectively improve the processing capacity and integrated level of data communication module,and reduce development cost significantly.
