Energy-aware fixed-priority scheduling for periodic tasks with shared resources and IO devices

International Journal of Embedded Systems (IJES), Vol. 12, No. 2, 2020

Abstract: Many researches have focused on energy management for the processor. However, DPM via I/O device scheduling for real-time periodic tasks with shared resources has drawn little attention. We address the problem of the I/O device energy consumption minimisation for shared resources. Furthermore, we present an energy-aware IO devices fixed-priority scheduling algorithm based on the RM scheduling. It contains two parts: job scheduling and device scheduling. Job scheduling ensures that each task can complete its execution within its deadline. Device scheduling decides to turn off devices to save energy. The experimental results show that it can achieve significant energy savings.
