摘要:
 为满足航空、航天等高安全领域对高可靠、低延迟、确定性的需求,SAE组织对IEEE 1394b协议局部进行了限制和改进,形成了SAE AS5643协议,其全称为用于军事和飞行器应用的1394b总线接口需求,目的是标准化Mil-1394b在军事和飞行器中的安全关键/任务关键应用中的方法途径。文中从实现系统确定性和可靠性两个方面来详细分析 SAE AS5643,提出Mil-1394b总线相比IEEE 1394b总线更适合作为完全关键的航空总线等高可靠场合的应用,提出了基于逻辑及FPGA实现AS5643协议的解决方案,并给出了实验结果,表明该解决方案满足设计指标,性能良好,提高了协议解析速度以及数据传输时间精度。
Abstract:
 To meet the requirement of high-reliability,low delay and determinacy for aviation field,SAE enhances the IEEE 1394b proto-col and has been standardized as the SAE AS5643 protocol,whose full name is 1394b bus interface requirements used for military and air-craft application,the purpose is to standard the way for Mil-1394b in safety and task critical application in military and aircraft. Analyze SAE AS5643 in detail from the determinism and reliability of system,present that the Mil-1394b bus is more suitable for the application as a critical avionics bus in high reliability occasions compared with IEEE 1394b bus. And propose a solution for the implementation of AS5643 protocol based on logic and FPGA. Experimental results show that the method meets the design indicators,with good perform-ance,and increases the speed of protocol parsing and time precision of data transmission.
