摘要 针对目前在线调度算法忽略预留任务特殊性的问题,基于现有的放置策略,定义并证明一个可靠的基于最大邻接边数的放置策略。提出一种基于亚可抢占性的任务调度算法,即剥夺预留任务所占用的可重构资源再进行统一离线调度。实验表明,与已有算法相比,该算法具有更高的任务接受率和芯片利用率,且并未明显增加运行时的开销。 This paper focuses on the online scheduling problem of real-time task based on two-dimension dynamic reconfiguration system,presents a placement strategy based on maximal adjacent edges,and proposes a Secondary Preemptable Scheduling Algorithm(SPSA) for hardware tasks,i.e.,deprive the reconfigurable resource of the reserved task,then performing unified off-line scheduling.Experiment shows the proposed algorithm has a higher task acceptance rate and a more effective chip utilization,without markedly runtime overhead increased.
