When the execution time of a program doesn’t become longer even if an instruction of the program is delayed by s cycles, the maximum of s is referred as the slack of the instruction. Thus the slack of a critical instruction is zero cycles. The slack value is stored to the prediction table to be a predicted value for the next time. This paper describes a slack predictor with global branch history. Exclusive-OR of an instruction address and global branch history is used to access the prediction table in the same way of the gshare branch predictor. The prediction accuracy is slightly improved as the length of global branch history is increased from 0 to 3.","subitem_description_type":"Other"}]},"item_4_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"30","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":"25","bibliographicIssueDates":{"bibliographicIssueDate":"2004-07-30","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"80(2004-ARC-159)","bibliographicVolumeNumber":"2004"}]},"relation_version_is_last":true,"weko_creator_id":"1"}}
