Abstract:
1. A network on chip (NOC) integrated circuit comprising: a first circuit portion coupled to a primary power supply and a backup battery power supply and including at least one initiator circuit configured to issue transaction requests, at least one network interface circuit coupled to said at least one initiator circuit, at least one router coupled to said at least one network interface circuit, and a controller coupled to said at least one router; and a second circuit portion coupled to the primary power supply and not coupled to the backup battery supply and including a target circuit coupled to said at least one network interface circuit and configured to receive transaction requests from said at least one initiator circuit via said at least one router when power is being supplied by the primary power supply; said controller being configured to receive an interrupt responsive to a power outage from the primary power supply, and to generate and send a notification to said at least one network interface circuit based upon the received interrupt via said at least one router of the power outage when a response is pending from the target circuit for a transaction request issued when power was being supplied by the primary power supply.
