Processing System With Interspersed Processors With Multi-Layer Interconnection

A method, comprising:

• receiving, by a particular communication circuit of a plurality of communication circuits, a message that includes routing information via a particular interconnection network of a plurality of interconnection networks, wherein each communication circuit of the plurality of communication circuits is coupled to the plurality of interconnection networks, and wherein the plurality of communication circuits is coupled to a plurality of processors in an interspersed fashion;
• selecting, by the particular communication circuit, a different one of the plurality of interconnection networks based on the routing information;
• and
• sending, by the particular communication circuit, the message to a different communication circuit of the plurality of communication circuits using a different interconnection network of the plurality of interconnection networks.

An apparatus, comprising:

• a plurality of layer switch circuits;
• and
• a plurality of direction switch circuits coupled to a of a plurality of interconnection networks, and wherein a particular direction switch circuit of the plurality of direction switch circuits is configured to:
• receive a message that includes one or more data words via a particular one of the plurality of interconnection networks coupled to the particular direction switch circuit;
• and
• forward the message, based on routing information included in the message, to a destination by relaying the message using one or more layer switch circuits of the plurality of layer switch circuits to a different one of the plurality of interconnection networks.
