Outline of Final Research Achievements

In order to develop software technologies supporting upcoming memory devices, we need an emulation technique that virtually creates a computer equipped with such a memory device. In this project, we developed a new emulation mechanism for next-generation memory devices. Our proposed mechanism dynamically adjusts the execution speed of a target program by using real-time monitoring data retrieved from processors. We confirmed that our mechanism precisely emulated any read/write latencies of memory device.

Academic Significance and Societal Importance of the Research Achievements

本研究で開発した次世代メモリのエミュレーション技術は、先行する同種の技術と比べて、メモリの読み込み遅延と書き込み遅延の違いを正確に再現できる点で優位性がある。次世代メモリの多くは、読み込み遅延と書き込み遅延が異なるため、このような特性を正確に再現する本開発技術は高い有用性を有する。本研究成果により、将来登場する新たなメモリ技術を見据えたソフトウェアの研究開発を行うことが容易になる。
