Abstract
A normalization circuit (24) which comprises a signed digit subtracter (25) coupled to operand registers (14, 19). The signed digit subtracter (25) subtracts the operands and inputs a signed digit difference to a pseudovalue converter (27). The pseudovalue converter (27) generates a pseudovalue in non-redundant format which contains its most significant non-zero bit in the selected bit position. The pseudovalue is output to a leading zero counter (28) which counts the number of leading zeroes in the pseudovalue.
