Abstract

In fast Floating Point Units, a Multiply Instruction has to be executed within one cycle. Consider a Multiplier of 61 x 61 bit. The state of the art solutions (Fig. 1) with an arraytype multiplier is too slow for the cycle. Another alternative with a customized multiplier array is uncertain in its result and needs very great effort (schedule and cost).
