摘要
In order to reduce the energy consumption of embedded systems, a subtask and executing time-based device scheduling policy (SEBDSP) was proposed by analyzing the drawbacks of EODSA (the energy-optimal device-scheduling algorithm) and IEODSA1 (the improved EODSA1). The SEBDSP divides tasks into several sub-tasks and manages I/O (input/output) devices in light of the executing time of the subtasks and the break-even points of the devices to extend the application area of the EODSA and the IEODSA1. The experimental results show that the average power consumption is respectively 31.94% and 4.95% lower with the proposed policy than with the EODSA and the IEODSA1.
