Outline of Final Research Achievements

To clarify the design space of future microprocessors after the end of moor’s law, this research project focuses on vertical integration technologies such as 2.5D and 3D technologies using a through silicon via (TSV). Since the TSVs have a high potential of shortening the latency and reducing the power consumption in/of microprocessors and computing systems, these technologies are expected to overcome the limits of technology scaling. In this research, we explore the design space of the future microprocessors by aggressively using TSVs in various stacking granularities. The evaluation results show that appropriate usage of TSVs with considering a trade-off among performance, power, and cost can drastically improve the energy efficiency of the microprocessors and computer systems.
