small and fast library dealing with signal processing
Tiny-DSP library contains c sources of a fast, tiny, portable and generic FFT (Fast Fourier transform) and inverse FFT. Supported are all power of two sizes (like 2,4,8,16,32,...) for one and two dimensional floating point arrays.
Aim is to develop a library of utility functions to efficiently simulate division, multiplication, mod, finding first 1/0 bit etc. (using shift and add/subtract) for software development on low cost dsp systems lacking these.
