摘要
时间触发协议具有的高确定性、无总线冲突、高可靠性、低延迟等优点,使其完全满足现代通信系统向可预测、可靠、实时的发展需求,成为适用于机载安全关键分布式系统的重要总线技术。文章对TTP/C协议的架构、时间同步和通信方式做出了分析,并提出了一种基于FPGA的TTP总线接口模块的实现方法。测试表明,模块实现方法合理、工作可靠。
Time-triggered protocol became an important bus technology for airbome safety critical distributed systems, because the advantages of high certainty, with no bus collision, high reliability and low delay, which can entirely satisfy modem communication systemt s requirement of being predictable, reliable and real- time. In this paper, the architecture of TTP/C, time synchronization and communication mode are analyzed, and an implementation method of TTP bus interface module based on FPGA is provided. The test shows that the method is rational in design and has high reliability.
