In an information processor formed of a program storage unit 2, a data pair production unit 3 and an operation unit 4 including an accumulator 41, when the sum of products of data ai and bi of the same generation SIGMA (ai*bi) is produced, a cumulative products instruction code MULA is read out from program storage unit 2. When a data pair related to the instruction code MULA is detected in production portion 3, a multiplication processing of the data pair and accumulation a processing of the multiplication result values using accumulator 41 according to the instruction code MULA are continuously executed in operation unit 4. Accordingly, the order of executing operation processing according to the instruction code MULA including the above-described multiplication processing and accumulation processing is not limited by the order of generations, and therefore data of different generations can be processed in parallel.
