（SFQ） 回路は，100 GHz 級の高速動作を特徴とし，ポストムーア時代の高速 ・低エネルギー集積回路技術として期待される．我々は，SFQ 回路によるコンピューティング基盤の実現に向け，デバイス／回路／アーキテクチャの協創によるアプローチを行っている．これまでに，SFQ 回路の性能を最大限に引き出す，ゲートレベル ・パイプライン手法を取り入れた算術論理演算器 （ALU） の動作実証を進めてきたが，本発表ではエネルギー効率の改善を目的として再設計した ALU について報告する．この ALU は，動作電圧を従来の 1/5 の 0.5 mV に下げることで，消費電力の大幅な低減を実現している．ニオブ 9 層プロセスを用いて試作した ALU をオンチップテストにより評価し，30 GHz の動作を確認した．消費電力は0.3 mW 以下で，エネルギー効率は 100 TOPS/W を超える．本稿では，実証した演算器に基づき，SFQ 回路における消費電力と動作速度のトレードオフ，冷凍機の冷却コストも考慮した消費電力あたりの演算性能，並びに，エラー許容によるエネルギー効率改善の可能性検討について議論を行う．","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":"2019-07-17","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"3","bibliographicVolumeNumber":"2019-ARC-237"}]},"relation_version_is_last":true,"weko_creator_id":"44499"},"id":198378,"updated":"2025-01-19T22:03:24.816955+00:00","links":{},"created":"2025-01-19T01:02:34.153651+00:00"}
