Abstract: Analyzing the advantages of RM (Rate Monotonic) scheduling algorithm and its disadvantages in actual execution, the SR-RM (Self-Regulating Rate Monotonic) scheduling algorithm is proposed to adjust the task execution period through tracking the actual execution time of assigned tasks and processor utilization. In addition, SR-RM engaged in decrease unscheduled task set to improve reliability through scout and predict environment transformation. Simulation tests revealed that SR-RM scheduling algorithm is available to the real-time implementation environment of reducing the miss rate of tasks with higher processor utilization.
