A Time-recursive DCT And DST Parallel Lattice Structure For VLSI Implementation
K. J. Ray Liu, C.T. Chiu · 1991
A new scheme employing the time-recursive approach to compute the discrete cosine transform (DCT) and discrete sine transform (DST) is presented. Using such approach, parallel lattice structure that can dually generate the DCT and DST simultaneously is developed. The resulting architecture is regular, module, and without global communication and can be applied to any transform size N.
