Design of Pipelined Based Dct Architecture For Image Processing Applications

摘要

Discrete Cosine Transform is considered to be an essential tool in image and video compression systems. Fast algorithms for achieving appropriate approximation of DCT transform have been developed for video processing systems to overcome high energy consumption. Usage of only additions and subtractions in the proposed design has led to substantial decrease in complexity along with area and power consumptions. In this paper a DCT architecture using only 12 additions without the usage of multipliers has been proposed. The proposed architecture is compared with the existing methods for power, area, speed and complexity. The proposed design can be used for video processing with very little reconfiguration.
