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.
