In this paper we propose a novel low-power Carry-Select Adder (CSA) design called Cascaded CSA (C2SA). Based on the prediction of the critical path delay of current operation, C2SA can automatically work with one or two clock-cycle latency and a scaled supply voltage to achieve power improvement. Post-layout simulations of a 64-bit C2SA in 180nm Technology show that C2SA can operate at a lower supply voltage, attaining 40.7% energy saving, while maintaining a similar (average) Latency Per Operation (LPO) compared to standard CSA
