This mechanism provides a fully-protected, time-boundable page translation scheme. The overhead for virtual address translation does not depend on neither total amount of physical memories nor the number of running tasks. This paper also describes the implementation of the single address space system on μ-PULSER, a real-time operating system which is to be used for autonomous mobile robots. In order to evaluate this system, several kinds of overhead were measured. Then the result proved better performance when the number of tasks was large. It was clear that the cost of updating page table is constant in this translation mechanism, and the predictability of entire system was improved significantly.","subitem_description_type":"Other"}]},"item_4_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"6","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":"1","bibliographicIssueDates":{"bibliographicIssueDate":"1996-08-26","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"79(1996-OS-073)","bibliographicVolumeNumber":"1996"}]},"relation_version_is_last":true,"weko_creator_id":"1"},"id":26055,"updated":"2025-01-22T19:10:12.793920+00:00","links":{},"created":"2025-01-18T22:56:46.691061+00:00"}
