SEMICONDUCTOR OPERATIONAL CIRCUIT

摘要

The present has as an object thereof to provide a semiconductor operational circuit which is capable of conducting calculations with respect to analog vectors at high speed and with high accuracy. The semiconductor operational circuit of the present invention is a semiconductor operational circuit which executes a predetermined operation with respect to a signal train of N signals A1, A2, ..., Ai, ..., AN numbered using a first integer i which changes from 1 to N, comprising a first means for generating an output signal M proportional to the sum of the signal train (A1 + A2 +,..., + Ai +, ..., + AN), a second means for generating an output signals proportional to the sum of the product of signal and a predetermined weighting constant Xi defined with respect to the first integer i (x1A1 + x2A2 +, .., + xiAi+, .., + xNAN) and a circuit for calculating fjM - gjS using L sets of constants defined with respect to a second integer which changes from 1 to L (f1, g1), (f2, g2), .., (fj, gj),.., (fL, gL) and generating an output signal having logic "1" or "0" in accordance with the results thereof. <IMAGE>
