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 normal-battery mode and 36 percent energy when the system is in low-battery mode at the expense of some QoS degradation.
