  • Abstract
    This paper presents some work in progress on fast and accurate floating-point arithmetic software for ST200-based embedded systems. We show how to use some key architectural features to design codes that achieve correct rounding-to-nearest without sacrificing for efficiency. This is illustrated with the square root function, whose implementation given here is faster by over 35% than the previously best one for such systems.
