To reduce runtime leakage-power, we propose a new instruction execution control strategy called Pipeline Blocking in which a set of processing is put into a temporally and spatially packed region to maximize leakage-energy saving by a power-gating technique. We propose an execution control method when L1 data-cache misses occur and also propose a fine-grain issue-width control technique. We evaluate the proposed strategy and the result reveals that the proposed method reduces leakage energy by 7.3% for the integer unit with 1.3% performance degradation on average, compared with a conventional technique.","subitem_description_type":"Other"}]},"item_3_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"95","bibliographic_titles":[{"bibliographic_title":"情報処理学会論文誌コンピューティングシステム（ACS）"}],"bibliographicPageStart":"83","bibliographicIssueDates":{"bibliographicIssueDate":"2009-09-18","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"3","bibliographicVolumeNumber":"2"}]},"relation_version_is_last":true,"weko_creator_id":"10"},"created":"2025-01-18T23:27:07.256225+00:00","id":66243,"links":{}}
