Architecture Design and FPGA Implementation of CORDIC Algorithm for Fingerprint Recognition Applications

Fingerprint recognition is one of the most popular methods used by Biometric identification systems for personnel identification. CORDIC algorithm provides wonderful solution to perform the math intensive operations at the cost of few components like adder, shifter, multiplexer.Etc. Such math intensive operations are required to perform during the image enhancement phase of finger print recognition process. In this paper CORDIC based architecture is proposed to evaluate almost all the trigonometric functions. This is implemented using XILINX ISE 13.2. Performance of the architecture is analyzed in terms of relative error.
