METHOD FOR CONSTRUCTING A DATA LINK BETWEEN TWO PROCESSORS IN AN NFC CHIP SET THROUGH A COST SAVING METHOD

摘要

PURPOSE: A method for constructing a data link between two processors in an NFC(Near Field Communication) chip set is provided to enable non-contact data link between an NFC controller and a host processor of the NFC controller.;CONSTITUTION: A first coupler(CP1) accesses a contact communication port of a first processor(NFCC), and a second coupler(CP2) accesses the contact communication port of a security processor. The non-contact coupling between the first and second couplers is constructed. Through the first and second couplers and at least one RF signal, a first data transfer signal is transmitted to a contact communication port of the second processor. A second data transfer signal is transmitted to the contact communication port of the first processor.;COPYRIGHT KIPO 2011
