Discrete cosine transform (DCT) is the most widely used transformation technique in the field of signal processing particularly in the areas of image data. This paper addresses the design of parallel architectures for computing DCT using CORDIC. It concentrates on indirect methods, which avoids decomposition of direct DCT equation. In this paper, CORDIC methodology has been used to simplify the traditional indirect techniques for the computation of DCT. The proposed methodology is CORDIC… Expand
