自動並列化コンパイラによる DVFS 及び clock gating による電力制御を適用し，現在幅広く利用されている Intel Haswell Core i7-4770K マルチコア上で評価した．Intel Haswell マルチコア上で，Web カメラからの画像の入力・人の顔の認識処理・画面描画というリアルタイムなシステム全域における消費電力の削減を行ったところ，1PE 逐次実行では電力制御なしの場合の 31.06[W] から電力制御ありの場合では 28.74[W] に，3PE で並列化実行した場合では電力制御なし場合のの 41.73[W] から電力制御の場合では 17.78[W] に消費電力を削減したことが確認され，物体認識処理におけるマルチコア用のコンパイラ自動電力制御の有用性が確認できた．","subitem_description_type":"Other"}]},"item_4_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"6","bibliographic_titles":[{"bibliographic_title":"研究報告組込みシステム（EMB）"}],"bibliographicPageStart":"1","bibliographicIssueDates":{"bibliographicIssueDate":"2015-02-27","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"20","bibliographicVolumeNumber":"2015-EMB-36"}]},"relation_version_is_last":true,"weko_creator_id":"11"}}
