ABSTRACT:
A method and apparatus for performing matrix multiplication used in image processing is described. A modified Booth encoding method is used to reduce the logic circuitry in processor modules used for calculating forward and inverse discrete cosine transforms. A set of products of image values and matrix coefficients are generated and provided to a set of multiplexers. The multiplexers provide preselected products to a set of accumulators. The accumulators combine the products to generate the set of transform coefficients at the accumulator outputs.
