Abstract
Floating-point processors capable of performing multiply-add (Madd) operations and incorporating improved intermediate result handling capability. The floating-point processor includes a multiplier unit coupled to an adder unit. In a specific operating mode, the intermediate result from the multiplier unit is processed (i.e., rounded but not normalized or denormalized) into representations that are more accurate and easily managed in the adder unit. By processing the intermediate result in such manner, accuracy is improved, circuit complexity is reduced, operating speed may be increased.
