1.By analyzing preemptions of real-time tasks in embedded systems underpreemptive EDF(Earliest Deadline First) schedule algorithm,we create a preemption model of periodic real-time tasks.通过对采用抢占式EDF算法的嵌入式系统中各实时任务抢占行为的分析 ,建立了一个周期性任务集的抢占模型 ,从数学上描述...
[OS92] and [SGS] discuss fault tolerance for the rate-monotonic sc heduling algorithm. [SGM97] dis- cusses fault toleran t sc heduling for non-preemptiv e real-time tasks. Most w ork has b een done with the assumption of a single fault in the system and the k ey idea here is ...
We propose a multi-task management scheme with multi-priority queues and analyze its timeliness performance based on a round-robin theoretical model, which leads to our novel design of the preemptive task scheduling algorithm to optimize the average waiting-time of all tasks. Finally, an adaptive...
in the set of such sequences produced under a non-preemptive scheduler. The solution is based on a finitary abstraction, an algorithm for bounded language inclusion modulo an independence relation, and rules for inserting synchronization. We apply the approach to device-driver programming, where ...
