3.3 Algorithm <strong>for</strong> the proposed multiplier<br />

needs to be (16+1) bit. So unnecessarily an extra bit is used. To avoid this incon-<br />

venience, normal binary operands are trans<strong>for</strong>med to diminished-one operands by<br />

subtracting one from normal binary representation of any number. So if A is an<br />

n+1 bit binary number, then the diminished-one representation of A which is an<br />

n bit number and denoted by d[A], is given by
