Abstract:
1. A coprocessor circuit for processing image data in digital form, comprising: a motion vector controller block for generating, starting from the image data, motion vector values including predictor data and macroblock data relating to a current macroblock of the image data to be estimated, the predictor data and macroblock data adapted to be stored at respective memory addresses; an address generator block for extracting respective memory addresses from said motion vector values; a predictor fetch block for retrieving said predictor data based on respective memory addresses extracted by said address generator block; a current macroblock fetch and distengine block for retrieving said macroblock data based on respective memory addresses extracted by said address generator block and for processing said macroblock data according to a given function; a decision block for collecting retrieved macroblock data as partial results and selecting the best result therefrom; and temporal noise reduction means attached at the output of the decision block to noise-reduce said image data.
