非精确任务集的容错单调比率调度

摘要

Meeting deadline and geting high throughput are the main objective of real-time system.They are both important,but sometimes incompatible,such as reserving resource for fault tolerance.We describe a new scheme,through making use of the fualt-tolerant rate-monotonic scheduling and imprecise computation,a real-time system can get high throughput when operating normally and can meet the deadline of critical tasks when there are one or more transient error.
