Abstract
In this paper, a low-power and high-quality preserving DCT architecture is presented. It is obtained by optimizing the Loeffler DCT based on the Cordic algorithm. The experimental results show that the proposed DCT architecture occupies 19% of the area and consumes about 16% of the power compared to the original Loeffler DCT. Additionally the good transformation quality is retained. In this regard, the proposed Cordic based Loeffler DCT is very suitable for low-power and high-quality CODECs, especially for battery-based systems
