| Popis: | This letter presents a 16-nm 496-core RISC-V network-on-chip (NoC). The mesh achieves 1.4 GHz at 0.98 V, yielding a peak throughput of 695 Giga RISC-V instructions/s (GRVIS), a peak energy efficiency of 314.89 GRVIS/W, and a record 825 320 CoreMark benchmark score. Unlike previously reported [1] , this new score was obtained without modifying the core benchmark code. The main feature is the NoC architecture, which uses only $1881~\mu \text{m}^{2}$ per router node, enables highly scalable and dense compute, and provides up to 361 Tb/s of aggregate bandwidth. |
