In the process of structure investigation based on acceleration of H.265 reference software, we proposed a new motion estimation algorithm utilizing efficient small area search capability and a decision method of inter prediction mode necessity utilizing intensity dispersion of pixels in each candidate prediction unit PU and reducing total coding time by half. In addition, we showed that the tile/line accessible cache for efficient motion estimation could reduce number of access misses by over one order of magnitude in the large scale matrix calculation.\n ","subitem_description_type":"Abstract"}]},"item_8_description_5":{"attribute_name":"内容記述","attribute_value_mlt":[{"subitem_description":"2012年度～2016年度科学研究費補助金(基盤研究(C))研究成果報告書","subitem_description_type":"Other"}]},"item_8_description_64":{"attribute_name":"科研費番号","attribute_value_mlt":[{"subitem_description":"24500059","subitem_description_type":"Other"}]},"item_8_publisher_30":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"三重大学"}]},"item_8_text_31":{"attribute_name":"出版者（ヨミ）","attribute_value_mlt":[{"subitem_text_value":"ミエダイガク"}]},"item_8_text_65":{"attribute_name":"資源タイプ（三重大）","attribute_value_mlt":[{"subitem_text_value":"Kaken / 科研費報告書"}]},"item_8_version_type_15":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_970fb48d4fbd8a85","subitem_version_type":"VoR"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"近藤, 利夫","creatorNameLang":"ja"},{"creatorName":"KONDO, Toshio","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"佐々木, 敬泰","creatorNameLang":"ja"},{"creatorName":"SASAKI, Takahiro","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"深澤, 祐樹","creatorNameLang":"ja"},{"creatorName":"FUKAZAWA, Yuki","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"大野, 和彦","creatorNameLang":"ja"},{"creatorName":"OHNO, Kazuhiko","creatorNameLang":"en"}],"nameIdentifiers":[{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2019-05-08"}],"displaytype":"detail","filename":"2018RP0068.pdf","filesize":[{"value":"89.6 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"2018RP0068","url":"https://mie-u.repo.nii.ac.jp/record/12446/files/2018RP0068.pdf"},"version_id":"365eff0a-d823-49f2-9543-f78e1188436f"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"動き検出","subitem_subject_scheme":"Other"},{"subitem_subject":"SIMD","subitem_subject_scheme":"Other"},{"subitem_subject":"ブロッキング","subitem_subject_scheme":"Other"},{"subitem_subject":"インター予測","subitem_subject_scheme":"Other"},{"subitem_subject":"H.265","subitem_subject_scheme":"Other"},{"subitem_subject":"キャッシュメモリ","subitem_subject_scheme":"Other"},{"subitem_subject":"スーパースカラ","subitem_subject_scheme":"Other"},{"subitem_subject":"行列計算","subitem_subject_scheme":"Other"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"jpn"}]},"item_resource_type":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"resourcetype":"research report","resourceuri":"http://purl.org/coar/resource_type/c_18ws"}]},"item_title":"動き検出用の高並列拡張命令セットの研究","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"動き検出用の高並列拡張命令セットの研究","subitem_title_language":"ja"},{"subitem_title":"Highly parallel instruction set extensions for motion estimation","subitem_title_language":"en"}]},"item_type_id":"8","owner":"15","path":["1692685141649"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2019-05-08"},"publish_date":"2019-05-08","publish_status":"0","recid":"12446","relation_version_is_last":true,"title":["動き検出用の高並列拡張命令セットの研究"],"weko_creator_id":"15","weko_shared_id":-1},"updated":"2023-11-17T05:55:30.247427+00:00"}
