  • Method and apparatus to calculate the difference of two numbers
    Patent number: 6754688
    Abstract: An apparatus and method for determining whether two operands are less than two are disclosed. A first module generates first detection bits from a first operand and a second operand, where the first detection bits indicate a difference of zero. A second module generates second detection bits from the first and second operands, where the second detection bits indicate a difference of one. A combiner combines the first and second detection bits to determine whether the difference of two numbers is less than two. The apparatus and method is used in determining to bypass normalization in floating point calculation.
