The sum from a floating point adder is normalized by an initial shift based on a prediction for the position of the leading one or zero in the sum. This leading-one/zero prediction is based not on the operands input to the adder, nor the result from the adder, but on the intermediate gen
Exponents are first combined together, in a way that varies with the type of floating point operation. A single intermediate exponent result is placed on an intermediate exponent bus. This intermediate exponent is adjusted upwards for any carry-out from the operation on the mantissas, or
