Lejos has been doing this for ages: http://lejos.sourceforge.net/
Lejos is about the same size on ARM. Lejos has been running on ARM micros for almost 6 years and on H8 for much longer than that.
Blog Doing Math in FPGAs Tom Burke 12 comments For a recent project, I explored doing "real" (that is, non-integer) math on a Spartan 3 FPGA. FPGAs, by their nature, do integer math. That is, there's no floating-point ...
