基于负载执行紧迫度的实时补偿任务调度策略TSCTTL

Real-time Task Scheduling Strategy Based on Load Execution Urgency

针对支持补偿性的实时任务模型,分析实时任务的系统负载执行紧迫度,进而提出基于负载执行紧迫度的实时补偿任务调度策略TSCTTL;通过实验仿真表明,依据实时任务的负载执行紧迫度来调度补偿任务,降低了系统任务的截止期错失率,并提高了系统收益。

For the compensatory support real-time task model,this paper analyzed real-time task system load execution degree of urgency, then put forward real-time compensation task scheduling strategy TSCTTL based on the load execu- tion degree of urgency. The simulation results show that scheduling compensation tasks according to the load execution degree of urgency of the real-time tasks reduces the system task deadline miss ratio and improves the system returns.
