Algorithms and Computational Methods: Swift CORDIC Algorithm for the Application of Discreet Cosine Transformation - Softcover

Inhaltsangabe

CORDIC, also known as the digit-by-digit method and Volder’s 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. 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. This processor reduces the problem of division and multiplication. In CORDIC processor we can compute the functions by using of shifter, adder and substractor. In present era CORDIC algorithm is used in many applications like Multimedia, Digital Signal Processing applications like Smooth Filters, DCT, and FFT etc. First CORDIC algorithm is converted into hardware so it was facing some problems like scale factor, time consuming etc.
