While a SIMD unit is a part of a processor, it evolves more rapidly than the integer unit of the processor. Since the use of an FPU (Floating Point Unit) and a SIMD unit is basically abandoned from the kernel, there can be places inside the kernel where a SMID unit works effectively to deal with a large amount of data processing. This paper describes our preliminary work to explore the possibility to utilize a SIMD unit in the kernel. We performed preliminary experiments by using UML (User Mode Linux) and show that data copying can be improved.","subitem_description_type":"Other"}]},"item_4_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"8","bibliographic_titles":[{"bibliographic_title":"研究報告システムソフトウェアとオペレーティング・システム（OS）"}],"bibliographicPageStart":"1","bibliographicIssueDates":{"bibliographicIssueDate":"2012-02-21","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"1","bibliographicVolumeNumber":"2012-OS-120"}]},"relation_version_is_last":true,"weko_creator_id":"10"},"created":"2025-01-18T23:35:05.709832+00:00","id":80708,"links":{}}
