ABSTRACT

Coordinate Rotation Digital Computer (CORDIC) discovered by Jack E Volder. It is a shift-add operation and iterative algorithm. CORDIC algorithm has wide area for several applications like digital signal processing, biomedical processing, image processing, radar signal processing, 8087 math coprocessor, the HP-35 calculator, Discrete Fourier, Discrete Hartley and Chirp-Z transforms, filtering, robotics, real time navigational system and also in communication systems. In this paper, we discussed about the CORDIC algorithm and CORDIC algorithm based finite impulse response low pass & high pass filter. We have generated the M-code for the CORDIC Algorithm and CORDIC Algorithm based FIR filter with the help of MATLAB 2010a.We also discussed about the frequency response characteristics of FIR filter.
