Shift of the B Register In the traditional architecture (see Fig 1), to generate the partial product, B(0) is used to decide between A and 0. While other blocks represent the time for ANDing with B bits and adding n-bit A The main aim is to acquire a high-performance multiplier with low power by replacing the existing shift and add method of multiplication [2, 3]. Multiplication by Fig. ADD(a,b) adds two integers giving a+b. 1 years ago by Krishna_Agrawal • 2. Multiplication using Bitwise operations. I want to store the multiplicand in the accumulator and the multiplicand in the X-register. In this method, you add number with itself and rotate the other number each time and shift it by one bit to left alongwith carry. It On currently available processors, a bit-wise shift instruction is faster than a multiply instruction and can be used to multiply (shift left) and divide (shift right) by powers of two.
