つのモジュールから構成され，その間を AXI ストリームでデータを流す．この実装法により，性能を向上するだけでなく，リソース消費量も抑制することができる．各モジュールで入力されたデータから自動的に必要 ビットサイズを検知することで，さらに性能を上げ，リソース消費量を抑制できる．Vitis HLS 2020.1 の結果により，1920 × 1080 のイメージについて，構築したシステムはおよそ

driving system, the techniques to generate depth-map in real-time are necessary for the users. Semi-Global Matching(SGM) has been widely accepted to derive depth information in the field of computer vision. Generally, GPU is always an acceptable choice to meet the requirements of real-time. However, the high energy and resource consumption on GPU brings a burden on edge devices. Thus, FPGA has been a promising platform for its benefit of energy efficiency and high-speed performance. With considering the maintenance, we choose Vitis HLS 2020.1 as our tool and achieve 45.45 fps on the input source of 1920 × 1080, which is 1.28× faster than the performance on GPU Tegra X2.","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":"18","bibliographicVolumeNumber":"2022-SLDM-197"}]},"relation_version_is_last":true,"weko_creator_id":"44499"},"id":216075,"updated":"2025-01-19T15:56:28.295244+00:00","links":{},"created":"2025-01-19T01:16:48.123892+00:00"}
