| Abstract: | A design and realization scheme of fingerprint gathering interface based on FPGA(Field Programmable Gate Array)is presented in this paper, which is used in the fingerprint identification and recognition system that will be integrated in the ASIC(Application Specific Integrated Circuit).The paper studies the hardware of the interface circuit and how to control the sweep fingerprint sensor to complete the task of high quality fingerprint gathering with hardware language VHDL. The results of test show that the fingerprint gathering interface can completely satisfy the requirement of the system. |
