1. Apparatus for performing operations on analog data obtained from a portion of a processing plane, said portion organizable into N rows, where N is an integer greater than one, and M columns, where M is an integer greater than one, said rows and columns forming intersections, said processing plane having information elements at the intersections of selected ones of said rows and columns, said apparatus including:

  • storage means for temporarily storing analog data from information elements at M columns and n contiguous rows of said processing plane, where 1<

    n<

    N, said rows identifiable by n successive integers between 1 and N, to form a n×

    M operation plane,n×

    m sources of weighting information, associated with a process to be performed on a neighborhood of said processing plane, said neighborhood comprising a plurality of elements arranged as a local subset of n rows and m columns of said processing plane, where 1<

    m<

    M, said sources of weighting information mapped with a one to one correspondence to the elements of said neighborhood,combining means for simultaneously combining said n×

    m sources of weighting information with selected n×

    m neighborhoods of said n×

    M operation plane, said combining means adapted to associate said sources of weighting information with said analog data such that the row order of the weighting information corresponds to the row order of the analog data and the same weight is used for the same relative position within each of said neighborhoods.
