Coarse-grained reconfigurable architectures deliver high performance and energy efficiency for computationally intensive applications like mobile multimedia and wireless communication. This paper deals with the aspect of power-efficient dynamic reconfiguration control techniques in such architectures. Proper clock domain partitioning with custom clock gating combined with automatic clock gating resulted in a 35% total power reduction. This is more than a threefold as compared to the single
