dc.description.abstractThis paper proposes energy efficient real-time multi-task
scheduling (EDF and RM) algorithms by using buffers. The
buffering technique overcomes a drawback of previous approaches
by utilizing the slack time of a system fully. It increases the CPU
utilization and averages the workload of a system, so it enhances
the effectiveness of the DVS technique. We target multimedia
applications where a slight buffering delay is tolerable within a
latency constraint. We modify the state transition and queue
handling mechanism of multi-task scheduling in the kernel. In
experiments, our algorithms achieve up to 44% of energy
consumption saving for EDF scheduling and 49% for RM
scheduling with realistic task set configurations and reasonable
machine specifications.
