Claim of US Patent No. 10,367,745

8. A Network-on-Chip (NoC) to be used in a programmable logic device, comprising:a plurality of nodes disposed in the programmable logic device that route configuration data within the programmable logic device;
a plurality of latches disposed in the programmable logic device coupled to the plurality of nodes;
a plurality of links disposed in the programmable logic device, wherein the plurality of nodes are communicatively coupled via the plurality of links; and
routing logic disposed in the programmable logic device coupled to the plurality of latches that sends routing values to the plurality of latches;
wherein the plurality of nodes:
in a first mode, dynamically routes a first set of configuration data within the programmable logic device based at least in part on available bandwidth in one or more links of the plurality of links in response to the plurality of latches storing an initial set of routing values;
stores the first set of configuration data as a desired routing pattern in the plurality of latches of the programmable logic device to enter a second mode; and
in the second mode, routes a second set of configuration data within the programmable logic device using the desired routing pattern stored in the plurality of latches.
