Hello folks,

I've recently discovered that the Cortex M3 doesn't support hardware floating point. I've never worked with 32-bit mcus and I am wondering how fast would the software fp operations be...

A quick search seems to indicate that Cortex M4 does support it, but I had troubles finding dev boards for it and from some comments I read it seems like it still lacks proper documentation.

Ideally, I'm looking for a hardware fp supporting 32-bit mcu that costs under 20$ and has available dev boards under 50$. Preferably available on digikey.

Any help would be very welcome since I planned ordering components on monday and I am on a relatively tight schedule.
