Picture plane is partitioned into blocks of P*Q samples and intra- and inter-block parallel processing s are simultaneously performed. The intra-block processing is based on Roesser's state-space model.\n1. Synchronization of inter-block parallel processing.\nBi-directional (horizontal and vertical) and one directional (vertical) ring coupled processing systems are considered. The horizontal and vertical state variables computed from one block are transferred to the next right and top blocks respectively. Timing condition that each processing system has no waiting to receive state variables is established.\n2. Algorithms for intra-block processing.\nTo increase the processing speed with decreasing of the number of operations per sample and with increasing parallel computation degree, zero-state and quasi zero-state block processing methods are proposed and compared with block processing method. Qusai block method is found to be superior to others.\n3. Efficient processing system for denominator separable transfer function.\nAs the block state matrix of the filter has high sparsity, the rows and columns are interchanged respectively to reduce the matrix size. as a result, some raising of the throughput of the system and some reduction of the number of required processors are achieved.\n4. Optimum design of one directional ring coupled system.\nOne directional system has advantage of lower frame latency than bi-directional system, where frame latency is defined as the time from beginning to the end of one frame processing. Optimum design conditions of the system to realize assigned throughput using minimum number of processors , i. e., the form and size of a block, number of simultaneously processed blocks, are found by computer simulation.","subitem_description_type":"Abstract"}]},"item_9_description_22":{"attribute_name":"内容記述","attribute_value_mlt":[{"subitem_description":"研究課題/領域番号:02650239, 研究期間(年度):1990 – 1991","subitem_description_type":"Other"},{"subitem_description":"出典：研究課題「零状態、零入力応答分離、ブロック処理による高速二次元ディジタルフィルタの実現」課題番号02650239\n（KAKEN：科学研究費助成事業データベース（国立情報学研究所）） \n（https://kaken.nii.ac.jp/ja/report/KAKENHI-PROJECT-02650239/026502391991kenkyu_seika_hokoku_gaiyo/）を加工して作成","subitem_description_type":"Other"}]},"item_9_description_5":{"attribute_name":"提供者所属","attribute_value_mlt":[{"subitem_description":"金沢大学工学部","subitem_description_type":"Other"}]},"item_9_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.24517/00067330","subitem_identifier_reg_type":"JaLC"}]},"item_9_relation_28":{"attribute_name":"関連URI","attribute_value_mlt":[{"subitem_relation_name":[{"subitem_relation_name_text":"https://kaken.nii.ac.jp/search/?qm=20019699"}],"subitem_relation_type_id":{"subitem_relation_type_id_text":"https://kaken.nii.ac.jp/search/?qm=20019699","subitem_relation_type_select":"URI"}},{"subitem_relation_name":[{"subitem_relation_name_text":"https://kaken.nii.ac.jp/ja/grant/KAKENHI-PROJECT-02650239/"}],"subitem_relation_type_id":{"subitem_relation_type_id_text":"https://kaken.nii.ac.jp/ja/grant/KAKENHI-PROJECT-02650239/","subitem_relation_type_select":"URI"}},{"subitem_relation_name":[{"subitem_relation_name_text":"https://kaken.nii.ac.jp/ja/report/KAKENHI-PROJECT-02650239/026502391991kenkyu_seika_hokoku_gaiyo/"}],"subitem_relation_type_id":{"subitem_relation_type_id_text":"https://kaken.nii.ac.jp/ja/report/KAKENHI-PROJECT-02650239/026502391991kenkyu_seika_hokoku_gaiyo/","subitem_relation_type_select":"URI"}}]},"item_9_version_type_25":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_ab4af688f83e57aa","subitem_version_type":"AM"}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2022-10-24"}],"displaytype":"detail","filename":"TE-PR-TAKEBE-T-kaken 1993-2p.pdf","filesize":[{"value":"122.0 kB"}],"format":"application/pdf","licensetype":"license_11","mimetype":"application/pdf","url":{"label":"TE-PR-TAKEBE-T-kaken 1993-2p.pdf","url":"https://kanazawa-u.repo.nii.ac.jp/record/61086/files/TE-PR-TAKEBE-T-kaken 1993-2p.pdf"},"version_id":"fd746ac4-a2a9-4084-9568-b8c4305b54e5"}]},"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":"零状態、零入力応答分離、ブロック処理による高速二次元ディジタルフィルタの実現","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"零状態、零入力応答分離、ブロック処理による高速二次元ディジタルフィルタの実現"},{"subitem_title":"Fast Implementation of Two-Dimensional Digital Filter using Block Processing Based on Separate Computation of Zero-State and Zero-Input Responses","subitem_title_language":"en"}]},"item_type_id":"9","owner":"18","path":["2842"],"pubdate":{"attribute_name":"公開日","attribute_value":"2022-10-24"},"publish_date":"2022-10-24","publish_status":"0","recid":"61086","relation_version_is_last":true,"title":["零状態、零入力応答分離、ブロック処理による高速二次元ディジタルフィルタの実現"],"weko_creator_id":"18","weko_shared_id":-1},"updated":"2023-07-27T12:03:56.373559+00:00"}
