摘要
随着JSF项目首先在航空器中采用IEEE-1394 b总线，使得该总线在航空电子系统中被快速广泛地使用。AS5643协议在IEEE-1394 b总线协议的基础上通过增加限制的方法，满足了新一代飞机管理系统总线对于高带宽、高确定性和高可靠性的要求。分析了基于飞机管理系统总线的基本拓扑结构和AS5643协议，阐述了一种基于FPGA逻辑设计实现AS5643协议的解决方案。通过实验验证，表明设计解决方案满足设计指标，性能良好，实现了飞机管理系统总线机载环境的应用要求。
Abstract
With the JSF project firstly using the IEEE -1394 b bus in the aircraft ,it maked the bus widely used in the Avionics Systems .The AS5643 protocol could meet the high bandwidth ,high assurance and high reliability requirements of the new generation of flight management system by adding to the limit method on IEEE-1394 b bus protocol .This paper analysis the basic topology structre on the flight man-agement system bus and the AS 5643 agreement ,then elaborate a solution which designs and implements AS5643 protocol on the FPGA.Finally,according to the experiment validation ,the results indicate that the design solution can meet the design specifications ,have the good performance ,and also implement the ap-plication requirements of the vehicle management system bus .
