摘　　要：TTCAN静态调度算法是基于表的静态调度,具有实时信号传输和带宽利用率方面的优势,但是实际应用中灵活性较差。本文提出了一种TTCAN的动态调度算法的实现方法。最后利用Matlab中的Stateflow工具对该算法进行仿真研究。仿真结果表明本文所提出的实现方法保证了传输的实时性,同时提高了应用的灵活性。Based on static table, static scheduling algorithm of TTCAN has the advantages of real time signal transmission and bandwidth utilization ratio; however it has low flexibility in practical applications. The implementation method of TTCAN dynamic scheduling algorithm is proposed in this paper. Finally, Stateflow tools in Matlab are used to simulate the dynamic scheduling algo- rithm. Simulation results prove that the proposed algorithm not only ensure real time transmission, but also enhance the flexibility in applications.
