This computer system is based on System on Chip (SoC) technology with SRAM-type FPGA. SoC technology has following advantage, 1) Flexibility of the system, 2) Reduction of development period by using existent IPs. However a SRAM type FPGA does not have strong tolerance against the SEU (Single Event Upset) phenomena. Therefore, the radiation may induce bit error in the static memory element and the configuration memory. In this paper, the radiation tolerant system with a soft core CPUS on the SRAM-type FPGA is proposed.","subitem_description_type":"Other"}]},"item_5_description_32":{"attribute_name":"資料番号","attribute_value_mlt":[{"subitem_description":"資料番号: AA0045441075","subitem_description_type":"Other"}]},"item_5_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"宇宙科学研究所"}]},"item_5_publisher_9":{"attribute_name":"出版者（英）","attribute_value_mlt":[{"subitem_publisher":"The Institute of Space and Astronautical Science (ISAS)"}]},"item_5_text_6":{"attribute_name":"著者所属","attribute_value_mlt":[{"subitem_text_value":"武蔵工業大学"},{"subitem_text_value":"東京理科大学"},{"subitem_text_value":"宇宙科学研究所"},{"subitem_text_value":"宇宙科学研究所"}]},"item_5_text_7":{"attribute_name":"著者所属（英）","attribute_value_mlt":[{"subitem_text_language":"en","subitem_text_value":"Musashi Institute of Technology"},{"subitem_text_language":"en","subitem_text_value":"Tokyo University of Science"},{"subitem_text_language":"en","subitem_text_value":"Institute of Space and Astronautical Science"},{"subitem_text_language":"en","subitem_text_value":"Institute of Space and Astronautical Science"}]},"item_access_right":{"attribute_name":"アクセス権","attribute_value_mlt":[{"subitem_access_right":"metadata only access","subitem_access_right_uri":"http://purl.org/coar/access_right/c_14cb"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"高原, 卓也"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"倉橋, 嘉裕"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"水野, 貴秀"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"斎藤, 宏文"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Takahara, Takuya","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Kurahashi, Yoshihiro","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Mizuno, Takahide","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Saito, Hirobumi","creatorNameLang":"en"}],"nameIdentifiers":[{}]}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"SRAM","subitem_subject_scheme":"Other"},{"subitem_subject":"計算機システム設計","subitem_subject_scheme":"Other"},{"subitem_subject":"ソフトコアCPU","subitem_subject_scheme":"Other"},{"subitem_subject":"SoC技術","subitem_subject_scheme":"Other"},{"subitem_subject":"FPGA","subitem_subject_scheme":"Other"},{"subitem_subject":"設計資産","subitem_subject_scheme":"Other"},{"subitem_subject":"シングルイベント・アップセット","subitem_subject_scheme":"Other"},{"subitem_subject":"耐放射線性","subitem_subject_scheme":"Other"},{"subitem_subject":"低コスト","subitem_subject_scheme":"Other"},{"subitem_subject":"研究開発","subitem_subject_scheme":"Other"},{"subitem_subject":"SRAM","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"computer systems design","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"soft core CPU","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"system on chip technology","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"FPGA","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"intellectual property","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"single event upset","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"radiation tolerance","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"low cost","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"research and development","subitem_subject_language":"en","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":"conference paper","resourceuri":"http://purl.org/coar/resource_type/c_5794"}]},"item_title":"ソフトコアCPUによる衛星搭載計算機の構築","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"ソフトコアCPUによる衛星搭載計算機の構築"}]},"item_type_id":"5","owner":"1","path":["1596","1891"],"pubdate":{"attribute_name":"公開日","attribute_value":"2015-03-26"},"publish_date":"2015-03-26","publish_status":"0","recid":"11680","relation_version_is_last":true,"title":["ソフトコアCPUによる衛星搭載計算機の構築"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-06-21T06:33:38.314547+00:00"}
