          <datacite:description descriptionType="Other">自動並列化技術と自動オフロード技術により，アプリプログラムを変更することなくメディア処理をヘテロマルチコア上で高速化する手法を提案する．メディア処理は高い演算性能を必要とするが，プロセッサの進歩はヘテロマルチコアへと進んでおりソフトウェアが複雑化する．本稿では，メディア処理アプリの特徴を利用し，コアへの処理の分割と並列化をアプリプログラマに隠蔽した高速化手法を提案する．実験では，提案手法により Window Media Player のソースコードを変更することなくデコード処理をオフロードすることができ，3 コアのアクセラレータを利用して 1.8 倍の性能向上が確認できた．</datacite:description>
          <datacite:description descriptionType="Other">This paper proposes new software architecture for media processing using the automatic parallelization and offload for hetero multicore. 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.</datacite:description>
