に備わっているシリアルリンクにより直接複数の FPGA を接続したマルチ FPGA システムは，低電力で高い性能を実現し，スケールアップが容易である点で有利である．マルチ FPGA の性能を引き出すためには，FPGA 間の通信方式の検討が重要である．そこで，本研究では安価な FPGA から構成されるマルチ FPGA システム，FiC (Flow-in-Cloud) 上でパケットスイッチ方式のルータを開発，実装した．そして実際のシステム上で，FiC システム上で現在運用されている STDM 方式のスイッチと，基本性能を比較した．その結果，2 ホップでの比較でタイムスロット 2 以上の STDM 方式に対しルータの通信性能がレイテンシの面から優れていることを確認した．また，24 台の FPGA から構成されるシステム上で 384 × 384 のサイズの行列に対する共役勾配法を実行し，パケットスイッチ方式は STDM 方式と比較し 1.73 倍の高速化に成功した．","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":"2020-01-15","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"6","bibliographicVolumeNumber":"2020-SLDM-190"}]},"relation_version_is_last":true,"weko_creator_id":"44499"},"created":"2025-01-19T01:05:13.826515+00:00","id":202678,"links":{}}
