Consider a digital circuit that multiplies two binary numbers by the repeatedaddition method. For example, to multiply 5 * 4, the digital system evaluates the product by adding the multiplicand four times: 5 + 5 + 5 + 5 = 20. Let the multiplicand be in register BR, the multiplier in register AR, and the product in register PR. An adder circuit adds the contents of BR to PR. A zerodetection signal indicates whether AR is 0. Develop the complete system block diagram, the ASMD chart Datapath internal architecture and the controller circuit for this digital system.
