Folks, I'm looking at a design problem that may need a floating point unit (single precision is fine). Part of the unknown at this point is that it would be running with the Microblaze embedded soft core on a Spartan
3S400. Do you have any recommendations for an FPU? Does such a configuration leave room (system gates, on-chip resources, etc) for anything else in terms of running a DSP type calculations (e.g. adaptive filters) and device control? I've seen the core provided by Quixilica, but would prefer to go to something free or open source due to the fact that I may find out it's not the solution, esp for the prototying phase. Thanks,-HT
