To satisfy these requirements, we proposed pipeline stage unification (PSU), and showed that it can reduce energy consumption than that of dynamic voltage scaling (DVS) which is currently employed. However, DVS and PSU are not exclusive techniques, and so further reduction of power comsumption can be achieved through combining them. This paper proposes a hybrid control mechanism which combines DVS and PSU to reduce power consumption more. This mechanism adapts the number of unifying stages, clock frequency, and supply voltage according to the throughput that the system requires, and consequently it reduces power consumption more than standalone DVS and standalone PSU. We evaluated our mechanism with various target throughputs. Our evaluation results show that our mechanism reduces power consumption by a maximum of 14% compared to the standalone DVS or by a maximum of 28% compared to the standalone PSU.","subitem_description_language":"en","subitem_description_type":"Abstract"}]},"item_10_identifier_60":{"attribute_name":"URI","attribute_value_mlt":[{"subitem_identifier_type":"HDL","subitem_identifier_uri":"http://hdl.handle.net/2237/10274"}]},"item_10_publisher_32":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"情報処理学会","subitem_publisher_language":"ja"}]},"item_10_rights_12":{"attribute_name":"権利","attribute_value_mlt":[{"subitem_rights":"ここに掲載した著作物の利用に関する注意 本著作物の著作権は（社）情報処理学会に帰属します。本著作物は著作権者である情報処理学会の許可のもとに掲載するものです。ご利用に当たっては「著作権法」ならびに「情報処理学会倫理綱領」に従うことをお願いいたします。 Notice for the use of this material The copyright of this material is retained by the Information Processing Society of Japan (IPSJ).
