摘要： A circuit for squaring a binary number X of n bits, x.sub.0 to x.sub.n-1, includes pre-processing circuits to form a group of all the products x.sub.i y.sub.j of the bits of number X, where i and j vary between 0 and n-1 such that i.ltoreq.j. The outputs of the pre-processing circuits provide words such that each word is formed by a succession, as complete as possible, of products selected among the products remaining from the group of products after forming the preceding word, each product x.sub.i y.sub.j of this succession being affected with a weight i+j+1 of the word if i is different from j, or with a weight 2i if i=j. Adders are connected to sum the words as the square of the number X.

摘要： A method of selecting motion vectors in a motion estimation system involves calculating values of an evaluation function. Each evaluation function value corresponds to a block of pixels of a reference window with respect to a current block of pixels and the relative position of the blocks is described by a motion vector. The method also involves determining the smallest value of the evaluation function and comparing the norms of the vectors associated with the smallest value. The vector having the smallest norm is selected from the associated motion vectors.

摘要： A decimation device for digital data sequences includes a multiplexer mounted in cascade with a calculator producing, alternately, during a first calculation cycle, the mean M.sub.i of at least two data sequences representing the pixels P(i,j) and P(i,j+1) in a line L.sub.i, and during a following calculation cycle, the mean M.sub.c. The mean M.sub.c is composed of the mean M.sub.i and of an intermediate sequence previously calculated and stored in a storage register arranged between an output for the calculation stage and at least one of the inputs to the multiplexer. The intermediate sequence represents the mean M.sub.i-1 of at least two data sequences representing pixels P(i-1,j) and P(i-1,j+1) in a line L.sub.i-1, where i varies from 0 to N-1 and j varies from 0 to M-1.
