Abstract目前大多数实时调度算法都依据单一的特征参数确定任务优先级,本文提出一种基于多特征协调的实时调度算法,对特定高优先级任务优先处理,并且对其他任务的调度不产生任何影响。同时,在系统超载的时候,有效避免了EDF算法性能的急剧下降。实验结果表明,该算法有效地保证了特定任务的调度优先级,相对于EDF算法性能有明显改进。; Currently,most of the real-time scheduling algorithms define the priority of task based on a single characteristic parameter. This paper presents a real-time scheduling algorithm based on the synthesis of multi-features. It processes the specific highpriority task and does not have any impact on the scheduling of other tasks. When system overload it can effectively avoid the sharp decline of the EDF (Earliest Deadline First) algorithm performance. Experimental results show that the algorithm effectively guarantee the priority of specific task scheduling,and the performance has significantly been improved compared with EDF algorithm.
