The development of low power systems gainedsignificant importance and impressive progress has been madein this domain in the recent years. However, despite moreefficient circuit technologies (made possible e.g. by the ongoingminiaturization of integrated circuits) as well as improvements inbattery technology, also the wayhowcomputations are logicallyperformed may have an effect on the required power consump-tion. In this invited paper, we consider reversible computation– an alternative computation paradigm which inherits certaincharacteristics and properties that may be of benefit for lowpower design. We review possible impacts to future developmentsand show how reversible computations can already been exploitedtoday. Finally, we sketch design challenges which, besides otherphysical and electrical issues, still prevent the full exploitation ofthis computation paradigm.
