| Abstract(in English) | Although dynamically reconfigurable processors have received an attention as a cost-effective off-load engine for mobile devices, techniques for reducing their consuming power have not been well investigated. Here, we analyzed the consuming power of MuCCRA-1, a prototype of dynamically reconfigurable processor, and applied two power reduction techniques: a traditional clock gating and a novel method called selective context fetching, which uses a default configuration data instead of fetching it from the context memory for unused components. Although the clock gating reduces only 0.7%, the selective context fetching achieves 13.2% power reduction. |
