【Abstract】 This paper realized a hardware platform design of fingerprint identification system based on DSP+FPGA coprocessor. Using FPGA as coprocessor to share data calculation and expansion interfaces,a high-effect fingerprint identification system will be realized,according to the improved algorithm of system. In this paper, the operand complex filter module in the fingerprint recognition algorithm has been implemented by Cyclone Ⅳ EP4CE75 of Altera corp., the quite complex control structure module in fingerprint recognition algorithm has been implemented by the software way based on the ADSP-BF70x DSP processor of Analog Devices Inc.. To improve the speed of Fingerprint Recognition Algorithm meets the requisition of digital signal processing’s real time in some situation.更多还原
