Abstract
An arithmetic logic unit includes structure for calculating in at least two stages, this structure including substructure for calculating in each of the at least two stages at least partially at the same time and substructure for ensuring the substructure for calculating in each of the at least two stages performs only one calculation at a time. Accumulators that work with pipe stages of a floating point unit may form all of part of the calculating structure. A method of performing calculations includes the steps of separating the calculations into at least two stages and separately accumulating the results of the stages using at least two accumulators, one each accumulator for each calculation at each of the at least two stages.
