In this paper, we present high throughput and power-efficient architectures for the implementation of integer DCT of different lengths to be used in upcoming High Efficiency Video Coding (HEVC). We have shown that efficient matrix-multiplication schemes could be used to derive parallel architectures for 1-D integer DCT of different lengths. Apart from that we have proposed three different flexible architectures which could be used for implementing the DCT of any of the prescribed lengths such… CONTINUE READING
