抄録

ムーアの法則が終焉を迎えつつある中、最近ではCPU以外のハードウェア、例えばよりエネルギー効率の良いFPGAの利用が増えている。しかし、CPU以外の異機種ハードウェアを利用する場合、Open Computing Language（OpenCL）の利用など技術力の障壁が高い。そこで筆者は、一度記述したコードを、配置するハードウェアに合わせて自動変換・構成し、高性能に動作させる環境適応型ソフトウェアを以前提案した。これまで、一部のアプリケーションのGPUへのオフロードは自動化されていた。本稿では、FPGAへのオフロードの第一歩として、アプリケーションの適切な対象ループ文を自動でオフロードする手法を提案し、その有効性を評価し、その有効性を確認した。
