A Review Paper on CORDIC Algorithm and Its Applications for Current Technology

Praveen Yadav ^[2] | Karan Singh ^[6]

Abstract: CORDIC (Coordinate Rotation Digital Computer), also known as the digit-by-digit method and Volders algorithm. This is a special-purpose digital computer for real-time airborne computation. In this, a unique computing technique is employed which is especially suitable for solving the trigonometric relationships involved in plane coordinate rotation and conversion from rectangular to polar coordinates. CORDIC algorithm is also applicable for square root, Logarithmic, Exponential function and for digital computer. In computation unit trigonometric functions are very crucial, at present many mathematical function require Sine, Cosine, Tangent etc, and by using this algorithm it easy to compute. With ongoing technology and limitations on power, operating frequency and energy consumption, if we are generating any trigonometry functions by using of multiplier, adder, divider those architectures consumes more hardware and computational time in- creases, for reduction of this problem CORDIC algorithm is converted into hardware form which is known as CORDIC processor. In this paper basically we did a comparative study between the existing CORDIC algorithm. In present era CORDIC algorithm is used in many applications like Multimedia, Digital Signal Processing applications like Smooth Filters, DCT, FFT etc.
