Dynamic voltage and frequency scaling technology is a promising way to save system energy. We proposed an energy-efficient scaling algorithm which utilizes both static and dynamic slack to adjust the frequency and voltage of a processor for running periodic tasks. Instead of excessively using up slack for the task under consideration, our proposed algorithm takes a global approach by intelligently assigning proper slices of slack to tasks and scaling the processor correspondingly. Experiments with an example system demonstrate that the energy consumption of our proposed algorithm is not larger than 3% of the theoretical limit.
