The present invention provides a device and method for applying 1-D and 2-D DCT and IDCT transforms to sets of input data, typically 8×8 or 16×16 matricies of coefficients. In one embodiment, the present invention provides input lines, logic to pre-add input values and generate operands and one or...http://www.google.fr/patents/US7117236?utm_source=gb-gplus-shareBrevet US7117236 - Parallel adder-based DCT/IDCT design using cyclic convolution
