NOC peripheral interconnect interrogation scheme

Abstract:

A network on a chip (NOC) peripheral interface (NPI) includes an NPI root, a plurality of switches coupled to the NPI root, and a plurality of NPI protocol blocks coupled to the plurality of switches. The NPI root, the plurality of switches, and the plurality of NPI protocol blocks are configured to route signals received from a master to a plurality of circuit blocks. A non-service command is routed to an intended circuit block of the plurality of circuit blocks. A switch of the plurality of switches or an NPI protocol block of the plurality of NPI protocol blocks generate a response message for a service command query with the destination address associated with the intended circuit block that is received from the master instead of routing the service command query to the intended circuit block.
