title = "An approach to energy-error tradeoffs in approximate ripple carry adders",
abstract = "Given a 16-bit or 32-bit overclocked ripple-carry adder, we minimize error by allocating multiple supply voltages to the gates. We solve the error minimization problem for a fixed energy budget using a binned geometric program solution (BGPS). A solution found via BGPS outperforms the two best prior approaches, uniform voltage scaling and biased voltage scaling, reducing error by as much as a factor of 2.58X and by a median of 1.58X in 90nm transistor technology.",
