摘要
时间触发架构具备资源利用率高、系统诊断精确、可组合性好的结构特点,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。以TTP/C和FlexRay两种典型的时间触发型总线为论述主体,通过对其节点结构、数据传输、时钟同步等方面的分析和比较,总结认为TTP/C总线将以其突出的高可靠数据传输机制,而被广泛应用于高安全性控制系统中;FlexRay总线以其独具的高灵活性将在未来分布式系统中发挥关键作用。
Time-triggered architecture has its own unique structure characteristics such as high resource utilization ratio, accurate system diagnostic and excellent composability can entirely satisfy modern com- munication system~ requirement of being predictable, reliable and real- time. This paper mainly concen- trate on two typical kinds of time- triggered bus which are T＇FP/C and FlexRay. Analyzed and compared through their node structure, data transmission, clock synchronize aspects, summed up and considered that,TTP/C will be widely used in safety- critical control system for its outstanding safety data transmis- sion mechanism and FlexRay could also make an important role in the future distributed systems with its unique high flexibility.
