Outline of Final Research Achievements

We designed and implemented the prototype computer architecture for the purpose of real-time regeneration of computer-generated hologram (electroholography) movie from successive 3D object model data. Our special-purpose computer was aimed to have advantages of scalability in parallel processing, power efficiency, and its compact size. Our computer consists of FPGAs(field-programmable gate array), GPUs (graphics processing unit), and general-purpose consumer PC parts. The FPGAs are electronic devices that can be configured by designers to have customized-data-processing instructions. We presented feasibility of our architectures by making trial product.

Academic Significance and Societal Importance of the Research Achievements

電子ホログラフィ像を表示するために必要とされるホログラムパターンのコンピュータシミュレーションには一般的に多くの計算時間が必要とされる。特にホログラフィ動画をリアルタイムに映す場合にその課題が顕著になる。汎用的で高性能かつ大型のコンピュータを利用することで解決を試みることはもちろん有用であるが,一方で(本研究課題のように)汎用性をある程度犠牲にすることでホログラフィに特化したコンピュータ構成を提案できれば,将来的なIoTを考慮した小型化の実現に近づく一助となることが期待できると考える。
