Application note EE-263 presents an optimized algorithm for a 256 point 16 bit FFT. It mentions that code has also been developed for a 4096 point FFT. Does anyone know where I can get sample code for the 4096 point FFT?
Thanks.

Hi david,
you can find the code examples for every DSP family on Analog web site. e.g. for ADSP-2136x family you can find code examples here.
Here are also parametrized FFT examples(single-channel -> one FFT is comuted, multi-channel -> two FFT's are computed simultaneosly), so you can choice FFT size.
RAD2 means that FFT size has to be 2^n, RAD4 means that FFT size has to be 4^n, where n is integer.
