If the point is fixed then it is fixed , if point floats then floating...
 

Re: fixed point dsp processor and floating point dsp process

A fixed-point DSP does only fixed-point arithmetic, and usually has
hardware to facilitate multiplication.

A floating-point DSP has extra hardware for floating-point addition and
multiplication (addition is a bit more involved than multiplication) and
often omits the hardware to facilitate fixed-poing multiplication.
Expect some difference in the size of a few registers.
