Patent abstract
The present invention provides an improved technique for performing a near processing path exponent difference in an arithmetic logic unit (ALU) of a microprocessor. In one embodiment, an apparatus having a separate logic circuit for near processing path and far processing path subtraction generates exponent difference signals using only two least significant bits of exponents of the two floating point operands to perform the exponent difference.
