ABSTRACT:
A method and apparatus for processing postnormalization and rounding in parallel in floating point arithmetic circuits. The fractional result of a floating point arithmetic operation is simultaneously passed to a normalized circuit and a round circuit, and the first two bit positions of the fractional result are examined. If the 2-bit format is 1.X the round circuit is activated; if the 2-bit format is 0.1X the fractional result is shifted left one position and the round circuit is activated; if the 2-bit format is in neither of the above formats the normalize circuit is activated. In no event is it necessary to activate sequentially the normalize circuit and the round circuit.
