摘要
对数控系统的多任务特殊性进行分析,并结合嵌入式运算资源的有限性,提出一种混合实时任务层次调度算法,在保证实时性的基础上,充分提高CPU的利用率,并给出该调度方法的层次调度模型和算法。
The particularity of multi-task schedule in CNC system was analyzed. A hierarchical scheduling algorithm of real-time tasks was presented considering limited computing capability of embedded system. The deadlines of real-time tasks were guaranteed and the utilization of processor was improved using the algorithm. The hierarchical schedule model and arithmetic were offered.
