What is the difference between fixed point dsp processor and floating point dsp processor?
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.
