一种基于FPGA的接口电路设计

Design Of Interface Circuit Based On FPGA

在航空电子系统中,经常需要对1553B总线和ARINC429总线进行双向数据转换以适应不同电子设备的接口要求。由于两种总线标准传输协议不同,传输速率和数据格式有较大差异,常规系统需要多种专业数据转换芯片以满足数据转换要求。本文介绍一种基于FPGA的通用数据转换模块设计。

GJB1553B bus and ARINC429 bus are widely used in aero electronfc system. For the transmission rate and principle of the two interface bus, a data conversion between them is needed. This paper will introduce a new design of interface circuit based on FPGA, which can meet the communication requirement without professional converting chips.
