On-line scheduling of real-time tasks for reconfigurable computing system

Abstract

Efficient task scheduling is very important for obtaining high performance in reconfigurable computing system. Previous researches mostly concentrate on the spatial placement of tasks, and did not pay enough attention to temporal factors. This paper focuses on the on-line scheduling of real-time tasks with known executing time, and introduces the notion of recognition-complete for scheduling algorithms, that is the algorithm can arrange the start time of a newly arrived task as early as possible. A new on-line scheduling algorithm is proposed, which achieves recognition-complete by using the technique of time window. The simulation results show that the proposed algorithm gains a prominent improvement in scheduling performance over previous algorithms
