Abstract

PURPOSE:To realize a big increment of the speed for multiplication by securing an optical digital pattern formation based on the multiplicand and the multiplier and then piling these digital patterns on each other to obtain the partial product between the multiplicand and the multiplier. CONSTITUTION:An optical digital pattern formation is secured based on multiplicand F and multiplier H, and then the optical digital patterns are piled on each other via the element which gives LED or the change of the transmittance to the digital signals. Thus the plicand is obtained to realize a big increment of the speed for multiplication.
