FPGA Implementation of FFT using CORDIC Processor for Fingerprint Application

Fingerprint applications are widely used to identify person’s authenticity. It is an important part of Biometric system which is widely accepted because of its accuracy. The frequency domain analysis of fingerprint plays an important role for authentication of noisy fingerprint images. In our project we proposed a new technique to extract features of fingerprint image for perfect matching. The FFT plays an important role for extracting the features. The idea is to reduce the computational complexity of FFT. This is achieved by implementing CORDIC processor for FFT. The CORDIC processor in our project is hardware efficient which minimises the computational complexity. The FFT to extract features of fingerprint is implemented using CORDIC processor which consumes 390 LUTs on VIRTEX 4 FPGA. KeywordsCORDIC algorithm
