Abstract
Abstract—This paper presents a technology mapping algorithm for field-programmable gate array architectures with dual supply voltages (Vdds) for power optimization. This is done with the guarantee that the mapping depth of the circuit will not increase compared to the circuit with a single Vdd. This paper also presents an enhanced clustering algorithm that considers dual supply voltages, honoring the dual-Vdd mapping solution. To carry out various comparisons, we first design a single-Vdd mapping algorithm, named SVmap-2, which achieves a 3.8% total power reduction (15.6 % dynamic power reduction) over a previously published low-power mapping algorithm, Emap [11]. We then show that our dual-Vdd mapping algorithm, named DVmap-2, can further improve total power savings by 12.8 % over SVmap-2, with a 52.7 % dynamic power reduction. Compared to the early single-Vdd version SVmap [14], DVmap-2 is 14.3% better for total power reduction. This is achieved through an ideal selection of the low-Vdd/high-Vdd ratio and the consideration of various voltage changing scenarios during the mapping process. Index Terms—Dual-supply voltages, field-programmable gate array (FPGA), power optimization, technology mapping.
