Abstract: Aiming at the high demand of portability and reusability for embedded system software development, a reasonable and effective schedule table synchronization algorithm is proposed. Through analysis on schedule table function, a real-time algorithm is used to calculate the synchronization time of the schedule table, which can achieve the synchronization between schedule table and synchronized counter, and increase the execution efficiency of the schedule table. The comparison results show that the algorithm can better ensure the system’s stability and real-time.
