SIGNAL PROCESSING ELEMENT CAPABLE OF IMPLEMENTING A HYBRID STRUCTURE TO SELECTIVELY PERFORM DCT-II, HAAR TRANSFORMATION, AND SLANT TRANSFORMATION BY A SINGLE CHIP AND AN IMAGE PROCESSING ELEMENT THEREOF

摘要

PURPOSE: A signal processing element and an image processing element are provided to perform a matrix computation selected by a switch unit from DCT matrix computation, Haar matrix computation, and Slant matrix computation for an input signal.;CONSTITUTION: A matrix computation unit(140) performs a matrix computation selected by a switch unit(120) from DCT matrix computation, Haar matrix computation, and Slant matrix computation. A butterfly structure computation unit(160) performs the butterfly structure computation for a single output signal of the computation units(130-150). A column permutation matrix computation unit(170) performs the column permutation matrix computation for the output signal of the butterfly structure computation unit.;COPYRIGHT KIPO 2012
