achieve both high clock rate and high IPC of microprocessors, clustered architecture has been proposed. In this architecture, instruction should be steered into \"the cluster with minimum Issue Delay\". But to detect such a cluster causes too complex calculation. Therefore, prior instruction steering algorithms use some approximations. This paper analyzes the precision of such approximations, and finds the room for improvement at concentration/distribution heuristics. To improve it, Local Distance Steering-a more precise approximation algorithm using Instruction Distance-is proposed. The evaluation by simulation shows that Local Distance Steering improves on performance 9.2% with Out-of-Order Issue architectures, 5.0% with FIFO Issue architectures.","subitem_description_type":"Other"}]},"item_3_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"93","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":"80","bibliographicIssueDates":{"bibliographicIssueDate":"2004-10-15","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"SIG11(ACS7)","bibliographicVolumeNumber":"45"}]},"relation_version_is_last":true,"weko_creator_id":"1"},"id":18441,"updated":"2025-01-22T22:44:35.594439+00:00","links":{},"created":"2025-01-18T22:51:10.692031+00:00"}
