Rfid Ip Core Design And Implementation Of Cf Interface Rfid Reader Design

The rapid development of VLSI made the sharp drop of the cost of of IC, as a result ,the price of RFID chip has dropped from 3~5 dollars to 3~5 cents.The drop of RFID IC promote the progress of the technology of RFID and its repid extension on the whole global with an evidence of the gradual progression of RFID Standards. For example, an Identification Card Standard ISO/IEC15693 distributed recently with an advantage over its former ISO/IEC14443 and ISO/IEC10536. ISO/IEC15693 is an important project of ISO/IEC JTC1/SC17/WG8(Work Group 8) which details on contactless integrated circuit card-vicinity cards and includes three parts:: Physical characteristics (Part 1);Radio frequency Power, Signal interface, Initialisation( Part 2) and Anticollision(Part 3).This Paper expatiates on the design of RFID IP(Intellect Property) Core using Top-Down methord of VLSI design which bases on the Standard of ISO/IEC15693 Firstly, this paper gives the methord of the design of RFID IP ,partion of modules and their function after makes a simple introduction of RFID and . ISO/IEC15693.The data transfer and signal control among these modules are introduced too. Secongly, this paper expatiates on several key modules and their design.On the design of RF interface,this paper make its focus on two modules,ASK Modulation Module using subcarriers and Demodulation Module using difference signals and their edge.On the design of Logical Control,this paper make its focus on the its key component, FSM(finite state machine) and gives the design of the FSM and all of operations of the FSM. Thirdly, on the innovation of algorithm,this paper gives a new methord of Anticollision loop which improves the BST(bool Insert),that is Dynamic BST.This methord improves the speed of data transfer and reduce data stream by find and do not transfer the same bits of data blocks.As a result the performance of the Dynamic...
