Sparse Hamming Graph: A Customizable Network-on-Chip Topology (In Proceedings of the 60th Annual Design Automation Conference, Jul. 2023) AbstractChips with hundreds to thousands of cores require scalable networks-on-chip (NoCs). Customization of the NoC topology is necessary to reach the diverse design goals of different chips. We introduce sparse Hamming graph, a novel NoC topology with an adjustable costperformance trade-off that is based on four NoC topology design principles we identified. To efficiently customize this topology, we develop a toolchain that leverages approximate floorplanning and link routing to deliver fast and accurate cost and performance predictions. We demonstrate how to use our methodology to achieve desired cost-performance trade-offs while outperforming established topologies in cost, performance, or both.Documentsdownload article:access preprint on arxiv: download slides: Recorded talk (best effort) | ||
