Workload characterization and cost-quality tradeoffs in MPEG-4 decoding on resource-constrained devices

In this paper, we propose system level dynamic power management of coarse-grained reconfigurable architectures through dynamic reconfiguration. The novelty of our approach is in two kinds of system level power management strategies for coarse-grained reconfigurable architectures considering the cost and quality-of-service (QoS) tradeoff by battery status. Experimental results on an MPEG4 video decoder show that our approach saves 17 percent energy when the system is in normalbattery mode and 36 percent energy when the system is in lowbattery mode at the expense of some QoS degradation.
