摘要： 该文将容错EDF调度算法和非精确计算技术结合起来,提高了算法的调度性能,使单处理器系统正常运行时具有高吞吐量,同时,在出现一个或多个偶发性软件错误时,仍能满足系统中关键任务的时限要求。

Abstract: A new scheme is described, through making use of the fault-tolerant EDF scheduling and imprecise computation, scheduling performance of algorithm is improved. Furthermore a real-time system can get high throughput when operating normally and meet the deadline of critical tasks when there are one or more transient error.
