C-NoC is a layered, scalable, configurable, and physically aware configurable NoC. It supports mesh, grid and torus topologies with simultaneous existence of both coherent and non-coherent traffic. It has configurable data bus widths, supports multiple clocking schemes, and is physically-aware with auto-pipelining and grouping of routers to meet timing requirements. C-NoC supports multiple protocols including CHI, AXI4/3 and AXI-lite, ACE and ACE-lite.
