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:
constructing a plurality of clusters, each of the clusters comprising a single router; for at least one of the plurality of clusters, connecting one or more cores to the single router of the at least one of the plurality of clusters, wherein a number of the one or more cores is based on a radix of the single router; and connecting said single router of a first one of the plurality of clusters to said single router of a second one of the plurality of clusters.
