Hi to all, I'm new to this forum and to Netduinos in general.

I have a question regarding the floating point unit of the netduino 2 plus, I'm searching a fast microcontroller and i hoped that the ND2+ was the right choice as it has the floating point unit that I need. From my early tests (some trigonometric computations) I was disappointed by the performance of it, I'm aware that being interpreted code it has to be much slower than compiled code, but I found that it performs slower (and I think that it shouldn't) than a microcontroller based on atmel sam3 that has not the FP unit, but with compiled code.

At this point I have a question, does .NETMF support the floating point unit of NP2+ ?

I'm quite sure (considering the obtained performances) that it does not, and i suspect that FP operations are computed in software.

If so the only alternative I have is probably to go native, but I must admit that I did not check yet how to do it.

And of course I have to find the way to go native *with* the FPU, as it is not straightforward that does exists a toolchain that support it.

It would be very appreciated if someone can give hints or tutorial to follow for going native with support to FPU.

Best regards to all,

Giuseppe
