A coprocessor circuit for processing image data in digital form, having a motion vector controller block for generating, starting from the image data, motion vector values that include predictor data and macroblock data relating to a current macroblock of the image data to be estimated and being adapted to be stored at respective memory addresses. Also included is an address generator block for extracting respective addresses from the motion vector values, a predictor fetch block for retrieving predictor data based on respective addresses extracted by the address generator block, a current macroblock fetch and distengine block for retrieving macroblock data based on respective addresses extracted by the address generator block and for processing the macroblock data according to a given function, and a decision block for collecting the retrieved data as partial results and selecting the best result therefrom.
