For intra-task DVFS, it is important to decide the location of checkpoints in a program, at which the frequency of processor could be changed to reduce the energy consumption. Furthermore, since insertion of checkpoints causes both time and energy overhead, it is expected that only limited and effective checkpoints should be inserted. In this work, execution trace based checkpoint extraction for intra-task DVFS is proposed, which consists of two steps. In execution trace mining, the behaviors and remaining execution cycles of conditional branch instructions are extracted and merged from a large number of traces, and this information is used to help search checkpoint candidates. In checkpoint extraction, checkpoint candidates are ranked in order of descending efficiency for energy reduction, and only the expected number of top-ranked checkpoints is inserted into the program. The proposed technique was evaluated by using the jpeg encoder and decoder benchmarks, and its effectiveness has been confirmed.","subitem_description_type":"Other"}]},"item_2_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"3744","bibliographic_titles":[{"bibliographic_title":"情報処理学会論文誌"}],"bibliographicPageStart":"3729","bibliographicIssueDates":{"bibliographicIssueDate":"2011-12-15","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"12","bibliographicVolumeNumber":"52"}]},"relation_version_is_last":true,"weko_creator_id":"11"},"updated":"2025-01-21T20:11:42.905147+00:00","created":"2025-01-18T23:34:17.488059+00:00","id":79575}
