queueing spin lock algorithms for exclusive accesses on multicore real-time systems have been proposed. Most of the algorithms are only for a single spin lock. Therefore they can not satisfy both of real-time property and scalability for increasing the number of cores in the nested spin locks. In this paper, we propose a preemptive priority inheritance queueing spin locks algorithm for nested spin locks. Moreover the design of a queueing spin lock hardware for supporting the algorithm is described. As the evaluation of the algorithm, acquiring and releasing time of nested locks and interrupt latency are measured with a FPGA evaluation board. In the evaluation, the hardware implementation achieved 3.11 times speedup against the software implementation. It is useful in a system that requests a high response.","subitem_description_type":"Other"}]},"item_3_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"146","bibliographic_titles":[{"bibliographic_title":"情報処理学会論文誌コンピューティングシステム（ACS） "}],"bibliographicPageStart":"133","bibliographicIssueDates":{"bibliographicIssueDate":"2011-05-12","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"3","bibliographicVolumeNumber":"4"}]},"relation_version_is_last":true,"weko_creator_id":"11"},"updated":"2025-01-21T21:40:35.656614+00:00","links":{}}
