Abstract

PURPOSE:To enable to operate square or mutual products in parallel, as to (n) sets of data in using a single multiplier, by providing a specific input multiplexer, a multiplier, and an output multiplexer respectively. CONSTITUTION:An input multiplexer 2 which interpolates a predetermined data including zero between given (n) sets of non-minus integer data (e.g., A-C) so that no interference is caused between square values of the result of multiplication and/or mutual products, is provided. Further, a multiplier(e.g., a square device) 4 which multiplies (n) sets of non-munus integer data interpolated with the said predetermined data and an output multiplexer 7 which separately picks up the square or mutual products of the non-minus integer data as a result of the operation of the multiplier 4, are provided. Thus, the square and/or mutual products as to the (n) sets of non-minus integer data are operated in parallel.
