Discrete Cosine Transform (DCT) is widely used in image and video compression standards. This paper presents low-power co-ordinate rotation digital computer (CORDIC) based reconfigurable discrete cosine transform (DCT) architecture. All the computations in DCT are not equally important in generating the frequency domain output. Considering the important difference in the DCT co-efficient the number of CORDIC iterations can be dynamically changed to reduce the power of consumption with improved image quality. The proposed CORDIC based 2D DCT architecture is simulated using Modelsim and the experimental results show that our reconfigurable DCT achieves power savings with improved image quality.
