When the real-time tasks are scheduled,μC/OS-Ⅱ takes use of single algorithm to assign the priority of tasks.Because of thesingularity of determinant standard of priorty,the high deadline missing ration of real-time tasks influences the real-time scheduling performanceseriously.This paper advances the assigning policy of priority of multi-parameter tasks and the task scheduling method in μC/OS-Ⅱ.Experimentalresults show that DMR of multi-parameter scheduling algorithm is 60.1%,and improvement of real-time scheduling performance.
