Design and Synthesis of Hybrid Nanophotonic Network-On-Chip Architectures

Abstract: Networks on Chip (NoCs) have emerged as scalable communication fabrics that can support high bandwidths massively parallel multi-core systems. However, traditional electrical NoC implementations still need to overcome the challenges of high data transfer latencies and large power consumption. On-chip photonic interconnects with high performance-per-watt characteristics have recently been proposed as an alternative to address these challenges for intra- chip communication. However, with increasing embedded application complexity, hardware dependencies, and performance variability, optimizing hybrid nanophotonic-electric NoCs requires traversing a massive design space. No prior work has addressed this problem to the best of our knowledge. We present the first effort in this direction for design and synthesis of hybrid nanophotonic network-on-chip architectures.
