摘要
为满足TTCAN的非周期和周期信息的实时性要求,提出了一种采用"权"的动态优先级提升算法。该算法用来提高仲裁窗中非周期信息的实时性。算法引入字母编码方式的遗传算法对系统矩阵时间调度表进行优化,并给出具体的计算方法和步骤。试验表明,该算法可以很好地满足网络中各信息的实时性要求。
To meet the real-time requirements for periodic and non-periodic information of TTCAN, the method based on dynamic priority of ＂right＂ to improve the real-time performance of non-periodic information in arbitration windows is proposed. Letter encoding genetic algorithm is introduced in the method to optimize the time scheduling for system matrix. Specific calculation method and procedures are given. The test shows that this method satisfies the requirements for real-time performance of all the information in the network.
