Patent ID: 8744347

Claim:
A method for routing incoming or outgoing application data in a Near Field Communication (NFC) system comprising: an NFC interface circuit performing contactless data sending and receiving; an NFC controller coupled to the NFC interface circuit; and at least a first and a second host processor coupled to the NFC controller, each of the first and second host processors configured to execute NFC applications and to process incoming application data received through the NFC interface circuit, or to supply outgoing application data to be sent through the NFC interface circuit, wherein the routing of incoming application data received by the NFC interface circuit comprises: conveying at least a first portion of incoming application data to a first destination point located in the first host processor and designated as an arbitration point for the routing of incoming application data; designating by the arbitration point a destination and processing point for the application data, the destination and processing point being located in the first or second host processor; and if the destination and processing point is located in the second host processor, conveying a second portion of the incoming application data to the destination and processing point and conveying outgoing application data sent by the destination and processing point to the NFC interface circuit.
