has been a growing interest in heterogeneous multicores because heterogeneous multicores achieve high performance keeping power consumption low. However, heterogeneous multicores force programmers very difficult programming. In order to overcome such a situation, this paper proposes a compilation framework which realizes high performance and low power. This paper also evaluates processing performance and the power reduction by the proposed framework on RP-X processor. The framework attains speedups up to 32x for an optical flow program with eight general purpose processor cores and four DRP (Dynamically Reconfigurable Processor) accelerator cores against sequential execution by a single processor core and 80% of power reduction for the real-time AAC encoding when we utilize an existing accelerator library.","subitem_description_type":"Other"}]},"item_3_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"79","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":"68","bibliographicIssueDates":{"bibliographicIssueDate":"2012-01-27","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"1","bibliographicVolumeNumber":"5"}]},"relation_version_is_last":true,"weko_creator_id":"11"},"created":"2025-01-18T23:34:50.818275+00:00","id":80353,"links":{}}
