Abstract
This paper presents a new approach to approximate various complex arithmetic functions for applications in wideband RF transceivers by using stochastic computing based on the piecewise linear (PWL) approximation. The optimized design parameters for PWL approximation are chosen by an optimization algorithm targeting the best tradeoff between hardware complexity and approximation accuracy. Then, this approximation is implemented by stochastic logic circuits. The proposed approach outperforms previous works based on Maclaurin expansions, Bernstein polynomial and finite-state-machine implementations while achieve similar computation accuracy. © 2017 IEEE.
