Tiled Processor Communication Fabric

A method, comprising:

• a computing system assigning communication resources of tiled fabric circuitry for a given cycle, wherein the fabric includes at least first and second instances of a tile, wherein the tile includes:
• client inputs configured to interface with client circuits of the computing system;
• tile inputs configured to interface with one or more other tile instances;
• and
• communication resources assignable to the client inputs and tile inputs, wherein the communication resources 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;
• wherein the assigning includes assigning communications 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 for the tile instance's inputs;
• and
• updating, by the computing system, priority information for a given tile instance of the fabric circuitry based on assignment results over multiple cycles.

A non-transitory computer readable storage medium having stored thereon design information that specifies a design of at least a portion of a hardware integrated circuit in a format recognized by a semiconductor fabrication system that is configured to use the design information to produce the circuit according to the design, wherein the design information specifies that the circuit includes:

• multiple client circuits;
• fabric circuitry that includes at least first and second instances of a tile, wherein the tile includes:
• 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, wherein the communication resources 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 configured to:
• 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 for the tile instance's inputs;
• and
• update priority information for a given tile instance of the fabric circuitry based on assignment results over multiple cycles.
