摘　　要：针对嵌入式系统软件开发对可移植性和可重用性要求高的特点,提出一种合理有效的调度表同步算法,通过对调度表的功能分析,采用实时算法计算调度表的同步时间,实现调度表和同步计数器的同步,以此提高调度表的执行效率。对比实验结果表明,该算法能够更好地保证系统的稳定性和实时性。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.
