| 摘 要： | 时间触发架构（TTA）为设计和实现高可靠性分布式嵌入式系统提供了软件和硬件的模型。在TTA系统中，全局时基和各种接口的精确定义，简化了节点间通信，保障了实时应用时限和错误检测。该文描述了TTA模型和TTA设计原则，并提出了基于TTA简单的车载节点模型。

| Abstract: | The TTA provides a software and hardware infrastructure for design and implementation of dependable distributed embedded systems. In the TTA, this global time is used to precisely specify the interfaces among nodes, and it aims to simplify the communications, to perform prompt error detection and to guarantee the timeliness. This paper discusses the architecture model of TTA, explains rational design and presents a single car node model based on TTA. |
