Abstract

Network-on-Chip (NoC) is a promising approach for supporting a heavy communication demand between all parts of high-performance modern nanoscale System-on-Chips (SoCs). Three-dimensional (3D) IC integration has become popular by reducing latency and energy consumption due to replacing long global interconnects with short vertical through silicon via (TSV) interconnects between different dies. Combining NoCs with 3D technology seems a good choice for achieving better performances than 2D. Although there exist good synthesis methods for designing energy- and communication-aware 2D-NoCs, there is still needs for 3D alternative. In this paper an energy-aware application-specific topology generation method for 3D-NoCs is proposed. This method is based on a heuristic optimization algorithm that partitions the application nodes among layers of the NoC architecture for an attempt to minimize the dynamic energy consumption. Proposed 3D method tested against a 2D alternative through several NoC benchmarks. Simulation results show that our approach outperforms its 2D counterpart in terms of energy and area.
