ABSTRACT:
A new partial product bit generator is used to generate a partial product bit PPji. In some embodiments, the partial product bit generator generates the partial product bit PPjifrom intermediate signals that are able to be generated concurrently, for example in two levels of combinatorial logic. The partial product bit PPjiis then able to be generated from the intermediate signal, for example in only one level of combinatorial logic. In such embodiments, a long series of combinatorial logic operations is not required.
