Due to the uncertainties in execution time of some tasks, this paper models each varied execution time as a probabilistic random variable. We use rotation scheduling and DVS (Dynamic Voltage Scaling) to minimize the expected total energy consumption while satisfying the timing constraint with a guaranteed confidence probability. Our approach can handle loops efficiently. In addition, it is suitable to both soft and hard real-time systems. And even for hard real-time, we have good results. | URI: | http://hdl.handle.net/10397/12663 | ISBN: | 0-7695-2682-9 | ISSN: | 2160-0511 | DOI: | 10.1109/ASAP.2006.69 |
