Abstract
A leading zero predictor (LZP) in parallel with the full subtraction operation correctly predicts the exact number of leading zeros of a subtraction result. Once the full subtraction operation is completed, the necessary shifts may be performed immediately, without a delay to determine the presence of leading zeros, and without need for a normalization corrector.
