Method of routing incoming application data in an NFC chipset, for identification of the application
First Claim
1. 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, whereinthe 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.

Abstract
A method for routing incoming or outgoing application data in an NFC system includes an NFC interface circuit performing contactless data sending and receiving. The routing of incoming application data received by the interface circuit includes routing at least a first portion of the incoming application data to a destination point located in the NFC system and designated as arbitration point of incoming application data routing; analyzing by the arbitration point the first portion of the incoming application data to identify the application for which the data is sent to the NFC system; designating by the arbitration point a point of destination of the application data and application processing; and routing a second portion of the incoming application data to the destination and processing point.
