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 ...
متن کاملFPGA Implementation of a Variable Precision CORDIC Processor
In this paper we present the FPGA implementation of a new word{serial CORDIC processor working with variable precision. It has been designed in such a way that it allows us to take advantage of the successive shifts in the coordinates involved in the CORDIC algorithm. This signiicatively reduces the total number of cycles required. Special attention has been paid to the design of the critical p...
متن کاملFpga Implementation of Dswg Using Cordic Algorithm
The Coordinate Rotational Digital Computer (CORDIC) algorithm is another classic approach for sine wave generation. This trigonometric iteration based approach relies on vector rotations for performing successive mapping between polar and rectangular co-ordinates (and vice versa)
متن کاملFpga Implementation of Cordic Algorithm Architecture
The Coordinate Rotation DIgital Computer (CORDIC) algorithm has been used for many years for efficient implementation of vector rotation operations in hardware. It is executed merely by table look-up, shift, and addition operations. Thus, the corresponding hardware can be implemented in very economic fashion. Subsequently, it has been applied for many performances.CORDIC has been implemented in...
متن کاملDesign and FPGA Implementation of CORDIC-based 8-point 1D DCT Processor
CORDIC or CO-ordinate Rotation DIgital Computer is a fast, simple, efficient and powerful algorithm used for diverse Digital Signal Processing applications. Primarily developed for real-time airborne computations, it uses a unique computing technique [7] which is especially suitable for solving the trigonometric relationships involved in plane co-ordinate rotation and conversion from rectangula...
