While media processing demands more and more computational power, it is difficult for a non-expert programmer to exploit hetero multicore that is a promising future processor architecture. The proposed method keeps programers away from parallelization and offloading for hetero multicore. Our experiments showed that the Windows Media Player speeduped 1.8 times by offloading the decoder to three cores accelerator without source code modification.","subitem_description_type":"Other"}]},"item_4_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"7","bibliographic_titles":[{"bibliographic_title":"研究報告モバイルコンピューティングとユビキタス通信（MBL）"}],"bibliographicPageStart":"1","bibliographicIssueDates":{"bibliographicIssueDate":"2010-03-19","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"59","bibliographicVolumeNumber":"2010-MBL-53"}]},"relation_version_is_last":true,"weko_creator_id":"10"},"id":69140,"links":{}}
