This paper presents an implementation and evaluation of a dynamic running mode switch mechanism of application programs. Our proposed mechanism has a characteristic of on-demand and on-the-fly mode switching of a process from user mode to supervisor mode and vice versa. While a process is in the supervisor mode, it is able to emit a system-call as a corresponding simple function call. Thus, it eliminates the overhead of a conventional trap-based system-call procedure. The evaluation shows that our implementation runs 800-900 clocks faster than a conventional system-call based implementation does.","subitem_description_type":"Other"}]},"item_4_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"56","bibliographic_titles":[{"bibliographic_title":"情報処理学会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":"49","bibliographicIssueDates":{"bibliographicIssueDate":"2005-08-03","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"79(2005-OS-100)","bibliographicVolumeNumber":"2005"}]},"relation_version_is_last":true,"weko_creator_id":"1"},"id":25519,"links":{}}
