But it has not achieved sufficient performance.  This paper describes a new scheme called frontend execution, which has a similar effect to value prediction. The instruction pipeline of a superscalar processor can be divided into two parts: the frontend is upper part than the instruction window, and the backend is the instruction window and the lower part of it.  Thus conventional superscalar processor has the execution stage in its backend.  Frontend execution is to execute ready instructions by function units posed in the frontend as well as the backend.  Evaluation result shows a processor with frontend execution is about 16.3 times faster than a normal processor.","subitem_description_type":"Other"}]},"item_4_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"17","bibliographic_titles":[{"bibliographic_title":"情報処理学会研究報告計算機アーキテクチャ（ARC）"}],"bibliographicPageStart":"13","bibliographicIssueDates":{"bibliographicIssueDate":"2004-05-14","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"48(2004-ARC-158)","bibliographicVolumeNumber":"2004"}]},"relation_version_is_last":true,"weko_creator_id":"1"},"id":23311,"updated":"2025-01-22T20:27:48.281854+00:00","links":{},"created":"2025-01-18T22:54:45.100359+00:00"}
