HIERARCHICAL ASYMMETRIC MESH WITH VIRTUAL ROUTERS

摘要

A network-on-chip configuration includes a first plurality of cores arranged in a two-dimensional mesh; a first plurality of routers, each of the first plurality of routers associated with a corresponding local one of the first plurality of cores, each of the first plurality of routers having a plurality of directional ports configured to provide connections to other ones of the first plurality of routers; a second plurality of cores disposed around a periphery of the two-dimensional mesh arrangement; and a second plurality of routers, each of the second plurality of routers associated with a corresponding local one of the second plurality of cores, and having a directional port configured to provide a connection to a neighboring one of the first plurality of routers.

1. A method, comprising:
for a network on chip (NOC) configuration comprising a plurality of cores interconnected by a plurality of routers in a mesh arrangement, generating a plurality of virtual routers configured to connect ones of the plurality of routers having one or more unused ports; and configuring each of the plurality of virtual routers to connect to an unused port of a router from the ones of the plurality of routers having the one or more unused ports.
