| Outline of Final Research Achievements |
The purpose of this study is to realize a highly energy efficient processor by using a fine-grain 3-D IC stacking technology. At first, this study aimed to improve components of the processor by the 3-D IC stacking. As a result, it has been shown that the fine-grain partitioning of the components could improve the performance and the power consumption of the arithmetic unit. As compared to the 2-D implementation, the 3-D stacked arithmetic unit improved the performance up to 20%, and the power consumption up to 10%. Next, in order to improve the energy efficient of the computing node which has several floating-point units, the fine-grain circuit partitioning method was considered and the design space was explored. As a result, As compared to the 2-D implementation, the 3-D stacked computing node achieved an 8% performance improvement and an 18% power consumption reduction in maximum.
