Herein described is a method and system of implementing integrated circuit logic modules that provide maximum efficiency and minimum energy dissipation. In a representative embodiment, a method of implementing one or more digital signal processing functions comprises determining one or more parameters associated with generating an optimal logic module. The one or more parameters may comprise the circuit area of the logic module and the processing time through a critical path of the logic module. In a representative embodiment, the system comprises a logic module that utilizes four full adders arranged in a tree configuration. In a representative embodiment, the logic module comprises a carry-save accumulator that provides maximum efficiency and minimal energy dissipation.
