Abstract
This paper presents a new run-time power management technique
for real-time embedded systems which consist of a voltage
scalable processor and power controllable peripheral devices. We
have observed that there exist significant trade-offs in terms of
energy consumption between the Dynamic Power Management
(DPM) scheme and the Dynamic Voltage Scaling (DVS) scheme
over a wide range of system operating conditions. The proposed
technique fully exploits workload-variation slack time by
partitioning the task into several timeslots and shut down the
unneeded peripheral device on timeslot-by-timeslot basis.
Through extensive simulations, the novelty and the usefulness of
the proposed technique are demonstrated.
