My audio codec drivers use float point operation heavily!
Does that mean that I can ONLY implement it on USER space ?

It's not impossible, but it's quite complicated, not supported
(no need), and architecture-dependent.

Anyway, codecs should be done in userspace.  That's how Linux does
software codecs.  Only audio output, or passing raw data to an audio
DSP, needs to happen in kernel space.
