Abstract

PURPOSE:To perform more effectively a parallel operation in a differential analyzer by performing, in parallel, action of a connection memory and that of the first and second adder action on and after the first and the second multipliers. CONSTITUTION:A plural number of operation input are added mutually on the first adder AD1 and an output from the adder AD1 is held in a latch circuit LAT until next pulses are generated according to timing pulse from an address counter CUA. Inclusions held on this circuit LAT are added to the first multiplier ML1, the second multiplier ML2 and an output circuit OZ by an adder assignment from connection memories MC1-MC4, a scale memory MS, a Y resistor RY and an R register RR and stated operations are done. In parallel to this operation, by assigning the memories MC1-MC3 with a stated address and by performing adding action in a next step for a fixed operation in memories MC1-MC3 and the adder AD1, an operation in a digital differential analyzer is done in parallel.
