Recently, methods that combine the concepts of Dynamic Voltage Scaling (DVS) and Dynamic Power Management (DPM) approaches have been proposed for a single task. This paper proposes Adaptive Power Management System (APMS), which utilizes useful features of both DPM and DVS and an existing pattern analysis algorithm, and new BET-based Task Partition Scheduling (BTPS). In order to determine the optimal processor speed that minimizes power consumption, the extra consumption required by the scheduler is compared with that reduced by BTPS. The proposed approach demonstrates better performance compared to existing power management schemes for not only a single task but multiple tasks.
