Outils pour une comparaison sans a priori entre arithmétique logarithmique et arithmétique flottante

This paper describes a library of parameterized arithmetic operators for manipulating high-dynamic numbers on FPGA. It support both floating-point and logarithmic representations. Along with its direct interest, that library allow application-specific comparisons of those two number representation systems. It is unbiased in the sense that it tends to reflect the state-of-the-art for both number arithmetic systems, and is freely available at MOTS-CLÉS : arithmétique, virgule flottante, système logarithmique, LNS, opérateurs matériels, FPGA, VHDL.
