But processors to support real-time operations should hold the rate of cache hit of high prior threads higher than other threads, because their cache miss needs a long access latency　to lower memory and it may cause dead-line miss. In order to realize a real-time mechanism, this paper proposes a new method to replace cache blocks with lower memory blocks based on priority. And if a cache miss happens, a high prior thread has access to lower memory, so that a latency of high prior thread to lower memory will reduce. These methods will be useful to keep dead-line because a cache access time of such a thread will reduce.","subitem_description_type":"Other"}]},"item_4_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"42","bibliographic_titles":[{"bibliographic_title":"情報処理学会研究報告計算機アーキテクチャ（ARC）"}],"bibliographicPageStart":"37","bibliographicIssueDates":{"bibliographicIssueDate":"2001-05-11","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"39(2001-ARC-143)","bibliographicVolumeNumber":"2001"}]},"relation_version_is_last":true,"weko_creator_id":"1"},"id":23610,"updated":"2025-01-22T20:18:16.490128+00:00","links":{},"created":"2025-01-18T22:54:58.341134+00:00"}
