With this memory system, simple compare operations, which are the core of selection and join, can be processed in the memory system.  Since the bit vector which is the result of comparisons is compact enough, the utilization of slow system bus can be improved rather than transferring a large amount of real data through the bus.  In addition to applying selection and join operations, CMP can also be applied to optimization of access path selection when combined with existing data transfer methods from memory. In this paper, we describe how CMP contributes to selection and join, and then, show the effect on the optimization of access path selection through simulation study.","subitem_description_type":"Other"}]},"item_3_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"189","bibliographic_titles":[{"bibliographic_title":"情報処理学会論文誌データベース（TOD）"}],"bibliographicPageStart":"177","bibliographicIssueDates":{"bibliographicIssueDate":"2007-06-15","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"SIG11(TOD34)","bibliographicVolumeNumber":"48"}]},"relation_version_is_last":true,"weko_creator_id":"1"},"updated":"2025-01-22T23:20:39.943571+00:00","created":"2025-01-18T22:50:26.443299+00:00","id":17439}
