FPGA-based Fingerprint Characteristics Hardware Study

In today's working life, when you are going to the bank to collect the money, doing online transactions, shopping, even to go and visit friends units, identity authentication is needed. In the traditional operation, we tend to use password encryption method. In fact, such a program encounter with problems. For example : passwords are easily forgotten, and it was easy for others to steal and so on.With the advancement of technology, fingerprint identification technology has started to enter our daily life. At present, many companies and research institutions in the world have achieved some of fingerprint recognition technology breakthrough technology, launched many new products, which have been utilized in many areas.Most of the traditional real-time signal processing systems using DSP & MCU structure, that is to be completed by the DSP image video and other digital signal processing, the completion of the external MCU design complete control of real-time signal processing system design. Traditional structure of real-time signal processing DSP & MCU system's weaknesses are : (1) the large number of DSP and MCU increase the processing time for a real-time signal processing systems (2) an increase in the PCB area (3) system with high costs.Many modern communications, real-time video images and high demands of real-time signal processing systems. Nowadays, the traditional programmable DSP has been unable to meet the requirements. Therefore, this paper presents the unloading of DSP algorithms using FPGA module with a large amount of hardware flow method. FPGA parallel signal processing overcomes the shortcomings of traditional structures and it has improved the processing speed and real-time signal processing systems to meet the modern requirements.In this paper, FPGA for DSP algorithm and unloading the large amount of calculation algorithm are a part of the overall design. The module design is mainly constituted by nine parts. Meanwhile, in a paper on the main module of the overall design process, in order to get the best modular design Papers on the same module used to compare different design options. Verilog hardware description language is used in the design on the platform Quartus II.
