Paper Abstract

New recursive VLSI architectures for arbitrary length discrete cosine transform (DCT) and inverse DCT (IDCT) are presented. Compared with previous methods, the proposed approach saves N-1 adders but requires one additional delay element for the DCT implementation, and saves (N/2) multipliers for the IDCT. The reduction in elements results from identifying common computations in the processing that generates the transform components.
