| Outline of Final Research Achievements |
Bottlenecks of both performance and power exist not in the arithmetic calculation or computation but in the data transfer between memory and arithmetic unit or in memory access. To overcome this problem, new computation model of Spatiotemporal Data Control is proposed. This model can explicitly specify both the timing of data movement and computation and the physical location of data. This research also investigated how to optimize execution by using this new model. The proposed method is applied to wide variety of computing systems, including three dimensional integrated VLSIs, high performance server systems, and sensor network systems. The preliminary experimental results reveal that the proposed method can successfully improve performance or reduce power consumption.
