Claim:
1. A method for collecting system information in a network on a chip (NoC) comprising a plurality of interconnected processing nodes, comprising: generating a dedicated packet at a source node of the plurality of interconnected processing nodes of the NoC, wherein generating the dedicated packet comprises generating routing information for the dedicated packet; transmitting the dedicated packet from the source node to a destination node of the plurality of interconnected processing nodes of the NoC traversing one or more intermediate nodes of the plurality of interconnected processing nodes of the NoC; modifying the dedicated packet with collected information at at least one of the intermediate nodes as the dedicated packet traverses a route from the source node to the destination node according to at least the routing information, wherein modifying the dedicated packets comprises pre-pending, appending, or combination thereof of the dedicated packet with consumed resources information at the intermediate node; and making the collected information of the dedicated packet available by the destination node, wherein the destination node makes the collected information available in response to a polling request by any node in the NoC other than the destination node.
