A semiconductor operational circuit capable of instantaneously processing in parallel a large quantity of information. The semiconductor operational circuit executes a predetermined operation of a first signal train of signals A1, A2, ..., AN-1, AN comprising N signals and a second signal train of signals B1, B2, ..., BM-1, BM (where N and M are positive integers) comprising M signals. The circuit includes a plurality of first operational circuits for executing a predetermined operation of Ai and Bi+n (where i is a positive integer and n is an integer and 1 </= i </= N, 1 </= i+n </= M) and generating an output signal Ci,n, at least one second operation circuit for generating the sum of a part, or the whole of the output signals of the first operational circuit or a predetermined signal Tn determined by the sum Sn, and a third operational circuit for finding the value Sn or Tn for a plurality of different n values and determining the n value for which the maximum or minimum value of Sn or Tn is given.
