Outline of Final Research Achievements

In contrast to traditional multi-threading platforms that are hard to improve power efficiency and hard to estimate performance, an acceleration technique that can fully utilize memory bandwidth and can easily fit to the performance and power model is established. A 12.5mm square prototype LSI of FU-array accelerator that can reduce the overheads of data movement and can work as vector mode has been designed. The power consumption is found to be only 0.88Watt and the performance per watt reaches 7.7GFlops/Watt.
