Abstract

In this paper, we address the problem of minimizing energy consumption of real-time tasks on variable voltage processors whose transition energy overhead is not negligible. Voltage settings with minimum number of transitions are found first and sequences of lower voltage cycles are evaluated to decide voltage for each cycle of every task. Experimental results demonstrate that our approach can reduce energy consumed by transitions from 41% to 8% and save more energy.
