(BTB) misses are performance bottlenecks in recent applications, and many instruction prefetchers have been proposed to eliminate them. In order for these prefetchers to work effectively, it is important to issue prefetch at a sufficiently early timing using a long prefetch distance. In addition, we found that increasing the prefetch distance improves not only the prefetch timing but also the coverage. Therefore, we propose a D-JOLT prefetcher that takes advantage of a large prefetch distance. D-JOLT is a prefetcher that learns and prediction by signatures using the information of function calls. D-JOLT achieves highly accurate prediction of a distant future with a hybrid configuration of prefetchers with different prediction accuracy and a signature that uses the number of consecutive return instructions. We evaluated D-JOLT with traces distributed in The First Instruction Prefetching Championship, and D-JOLT achieves a 52.0% performance improvement over a processor without an instruction prefetching and a 21.5% performance improvement over the state of the art prefetcher.","subitem_description_type":"Other"}]},"item_4_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"8","bibliographic_titles":[{"bibliographic_title":"研究報告システム・アーキテクチャ（ARC）"}],"bibliographicPageStart":"1","bibliographicIssueDates":{"bibliographicIssueDate":"2020-07-23","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"1","bibliographicVolumeNumber":"2020-ARC-241"}]},"relation_version_is_last":true,"weko_creator_id":"44499"},"updated":"2025-01-19T19:28:35.026980+00:00","created":"2025-01-19T01:08:20.808906+00:00","id":206273}
