Abstract

This paper presents a 16nm 496-core RISC-V network-on-chip (NoC). The mesh achieves 1.4GHz at 0.98V, yielding a peak of 695 Giga RISC-V instructions/s (GRVIS) and a record 812,350 CoreMark benchmark score. The main feature is the NoC architecture, which uses only 1881μm² per router node, enables highly scalable and dense compute, and provides up to 361 Tb/s of aggregate bandwidth.
