Duato の十分条件に基づき,仮想チャネルを用いずに低ホップ数経路を構築可能なルーティングの構成手法を探求する.具体的には,スパニングツリー上で Deadlock-Free な Routing Subfunction を定義する.さらに,ツリー上のチャネルに幅優先探索に沿って順序付けを行い,Duato の定義した 4 つのチャネル依存を考慮したAdaptive channel の追加を行う.ルーティング時に最短経路上の Adaptive channel を用いることにより,従来の Up*/Down* ルーティングに比べ,低負荷時の通信遅延を最大で 9.4 % 削減可能であることが分かった.","subitem_description_type":"Other"}]},"item_4_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"6","bibliographic_titles":[{"bibliographic_title":"研究報告システムとLSIの設計技術(SLDM)"}],"bibliographicPageStart":"1","bibliographicIssueDates":{"bibliographicIssueDate":"2022-01-17","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"20","bibliographicVolumeNumber":"2022-SLDM-197"}]},"relation_version_is_last":true,"weko_creator_id":"44499"},"updated":"2025-01-19T15:56:26.125473+00:00"}
