Abstract
A predictor provides as a pixel block of a current image a set of p target pixels of the preceding image so that each target pixel corresponds in the image to the adjacent pixels of the current pixel shifted by a predetermined motion vector. The predictor includes a search memory, each cell of which is independently addressable in read/write mode; three write decoders for simultaneously addressing in write mode three cells of three portions of the memory; p read decoders for simultaneously addressing in read mode p cells of p distinct sub-portions of the memory; and for controlling the write decoders so that p successive writings of data of the same nature corresponding to p adjacent points in the image are achieved in each of the p sub-portions.
