I am working on converting a floating point MATLAB code into fixed point C code. The code is to be run on a DSP platform, the specifics of which are yet to be decided.
I'm new to floating point to fixed point conversion and am facing quite a few challenges.
My questions are:
What is the best way for me to start and where should I start, because the topic is quite confusing.
My MATLAB code is basic filtering code; there's FFT, windowing followed by IFFT. Windowing seems simple enough as its multiplication, but I'm totally lost when it comes to FFT and IFFT.
