摘要
控制器局域网(CAN)协议被广泛运用在分布式嵌入式系统中,研究表明共享时钟调度算法能有效的将基于CAN的微控制器与时间触发网络结构结合起来。文章指出了共享时钟调度算法存在的一些不足,并且提出一种改进的共享时钟调度算法,通过构建一个实际系统验证了两种算法在CAN通信中的性能,结果显示改进的共享时钟调度算法是对原算法的一种有效补充。
The Controller Area Network (CAN) protocol is widely applied in the development of distributed embedded systems. Studies indicate that the "Shared-Clock" (S-C) algorithm could be used to implement the combination of CAN-based microcontrollers with the time-triggered network architectures. This paper explores some limitations of the existing S-C algorithms, and proposes a new algorithm. The experiment suggests that the new algorithm is an effective supplement to the original shared-clock algorithms.
