摘要：

This paper presents software tools that convert the C/C++ floating point source code for a DSP algorithm into a fixed point simulation model that can be used to evaluate the numerical performance of the algorithm on several different fixed point platforms including microprocessors, DSPs and FPGAs. The tools use a novel system for maintaining binary point information so that the conversion from floating point to fixed point is automated and the resulting fixed point algorithm achieves maximum possible precision. A configurable architecture is used during the simulation phase so that the algorithm can produce a bit-exact output for several different target devices.
