Claim of US Patent No. 10,185,672

1. A multichip system, comprising:a first integrated circuit chip including:
a first plurality of processors;
a plurality of memories;
a first plurality of routers coupled together to form a first primary interconnection network;
a plurality of interface units coupled together to form a secondary interconnection network, wherein each interface unit is coupled to a respective processor of the first plurality of processors and a respective router of the first plurality of routers;
a bus controller coupled to at least a particular interface unit of the plurality of interface units;
wherein the first plurality of processors, the plurality of memories, and the first plurality of routers are coupled together in an interspersed fashion; and
a second integrated circuit chip coupled to the first integrated circuit chip via an inter-chip interconnect, wherein the second integrated circuit chip includes a second plurality of processors;
wherein a particular processor of the second plurality of processors is configured to send first data, via the inter-chip interconnect, to the bus controller; and
wherein the bus controller is configured to:
relay the first data to the particular interface unit; and
arbitrate requests for access to the particular interface unit from a plurality of circuit blocks.
