【摘要】 针对同构多处理器系统提出一种基于双优先级的实时任务调度算法。对偶发任务进行接受测试,进一步提高了系统对偶发任务调度的成功率。模拟结果表明,当多核处理器系统利用率达到极限时,该算法依然能够在完成强实时周期任务的成功调度前提下,保证软实时周期任务和偶发任务具有较高的调度成功率。更多还原

【Abstract】 This paper presents a real-time task schedule algorithm based on dual priority for the homogeneous multi-processor system.Aiming at the character of sporadic tasks,the algorithm pretests the sporadic tasks and further improves the success rate of sporadic tasks schedule.The simulation results show that when the multi-core processor system utilization is at the limit,the algorithm is still able to schedule the hard real-time periodic tasks successfully and ensure the high success schedule rate of soft real-time periodic tasks and sporadic tasks.更多还原
