More Information
Summary:Techniques are disclosed relating to processor communications fabrics. In some embodiments, a processor includes multiple client circuitry and fabric circuitry that includes at least first and second instances of a tile. The tile may include: client inputs configured to interface with client circuits, tile inputs configured to interface with one or more other tile instances, and communication resources assignable to the client inputs and tile inputs. The communications resources may include: multiple internal links, client outputs configured to interface with client circuits, and tile outputs configured to interface with one or more other tile instances. Control circuitry may, in a given cycle, assign communication resources of a given tile instance to at least a portion of the client inputs and tile inputs for a next cycle, based on priority information. The control circuitry may update priority information based on assignment results over multiple cycles.
