Abstract

This paper describes the design of a low-power DCT (Discrete Cosine Transform) architecture using varies techniques. The low-power design is one of the most important challenges to maximize battery life in portable devices and to save the energy during system operation. Discrete Cosine Transform (DCT) is one of the most popular lossy techniques used in image and video compression standards. Several algorithms have been proposed to implement the DCT. So we have to implemented the multiplier-less CORDIC algorithm. CORDIC (Coordinate Rotation Digital Computer) algorithm is a class of shift- add algorithm for rotation vector and plan which is usually used for the calculation of trigonometric functions. The whole design is simulated with Xilinx ISE 14.1 software and results are completely consistent with DCT.
