FlexSword can execute several multimedia applications bacause of dynamic reconfigurable structure. In uni-processor system, FlexSword drive less time than the host processor. For time and area effeciency, multi processor share one FlexSword. Although FlexSword is a powerful accelerator, its performance is limited on uni-processor system because the host processor is not powerful enough to utilize it. Therefore resource sharing of FlexSword on multi-processor system is required. In this paper, we propose the sharing mechanism of FlexSword for multiprocessor system. We enhance the area-efficiency by sharing the FlexSword with multi processors. We evaluate the area-efficiency in simulation and get the result of up to 70% enhancement of area-efficiency when four processors share one FlexSword.","subitem_description_type":"Other"}]},"item_4_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"9","bibliographic_titles":[{"bibliographic_title":"研究報告計算機アーキテクチャ（ARC）"}],"bibliographicPageStart":"1","bibliographicIssueDates":{"bibliographicIssueDate":"2009-07-28","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"16","bibliographicVolumeNumber":"2009-ARC-184"}]},"relation_version_is_last":true,"weko_creator_id":"10"},"id":62712,"links":{}}
