Optimisation d'opérateurs arithmétiques matériels à base d'approximations polynomiales

This article presents a method for the optimisation of hardware arithmetic operators dedicated to function evaluation using polynomial approximations. Using recent tools, the method reduces the size of the polynomial coefficients and the intermediate values while keeping the total error bounded (approximation and evaluation). It leads to small and fast operators with a good numerical quality. The method is illustrated on several examples implemented on FPGA circuits.
