芯片间时间触发消息堆叠调度方法

To ensure the strict time determinism of message transmission between avionics communication tasks, time-triggered (TT) communication methods are also applied to the off-chip interconnection network. When avionics tasks have multiple operation modes, the time-triggered schedules between chips belonging to different modes will overlap and occupy time slots. The stacking scheduling method for time-triggered messages in off-chip network, which can reduce the queuing delay of application layer messages due to the waiting TT time window, is proposed to improve the flexibility and efficiency of using network resources,. Simulation experiments show that compared with the super scheduling method, the stack scheduling method can reduce the total end-to-end delay of TT messages in the off-chip interconnection network and the average time slot occupancy rate of the link. For scenarios where the end-to-end delay time is long and the average link bearer message transmission is large, the effect of using the stack scheduling method to reduce the end-to-end delay is more significant.
