Can you tell us a bit more about your requirements for floating point maths?
I write control software for jet engines in custom build microcontrollers with no floating point support. Very often we find something we THINK we might have to use floating point for and discover that we dont!
The most frequently used solution is to establish your maximum and minimum values and instead of scaling your calculations to +/- 1, they are scaled from -32768 to 32767 instead.
Failing that, another option is to use the FPGA as an I/O device and do any floating point work in a Windows host.
