    摘要:

    AS5643总线是为了满足航空飞行器中高速实时数据传输的应用需求而提出的一种高速总线技术,其以IEEE 1394b协议为基础并对该协议的实时性、确定性、可靠性以及消息传输机制进行增强改进。为了推动AS5643总线技术的应用,针对AS5643总线协议IP核进行研究,设计了基于FPGA的AS5643总线协议模块,并搭建了多节点的总线互联系统对AS5643总线协议模块的功能和性能进行测试。测试结果验证了所设计协议IP核满足AS5643协议规范,实现了高带宽的数据传输,能够满足航空飞行器的应用需求。

    Abstract:

    AS5643 high speed serial bus is proposed to meet the realtime high speed data transmission application requirements in aviation aircraft building upon the foundation of IEEE 1394b protocol which ameliorates and enhances its realtime capability, certainty, reliability and message delivery mechanism. To promote the application of AS5643 technology, a study is conduct on AS5643 protocol to design the AS5643 LLC IP core transmission node conformed to the protocol based on FPGA. We build an integrated system with several nodes to validate the functions and performances of AS5643 node by using the test equipment to monitor and analyse the transactions on the serial bus. The experiment and test results show that this AS5643 LLC IP core conforms with AS5643 protocol which can achieve reliable high bandwidth of data transfer in the aeronautic application field.
