In particular, it collects results on 72 single precision libm functions with respect to two different target devices. For each function, two different implementations are considered. The first one is obtained by passing option –soft-float and performing the high-level synthesis using the bambu softfloat library, while the second one is obtained performing the high-level synthesis using the FloPoCo generated cores, passing option –flopoco.
