Abstract

CORDIC (Co-ordinate Rotational Digital Computer) plays a major role in shift and add operation in trigonometric, hyperbolic function in shifting and adding cosine, sine, tangent function. In this paper CORDIC is used in Discrete cosine transform as a multiplier unit. DCT is modified using column bypass and row bypass technique to increase the speed and to reduce the delay with less complexity for that purpose a technique called factor sharing method is proposed in CORDIC architecture which is implemented using video compression for real time application. CORDIC using DCT is done using MODELSIM6.4a by taking video compression as a input, where the video is been converted into text file using the MATLAB software.
