I want to program the FFT 32K in Parallella.
Input: 16bit 200Msps
Processing speed: latency <300nsec

Please tell me the structure and algorithms.

There is plenty of information about FFT here already on the forum and on the Parallella blog (http://www.adapteva.com/white-papers/using-a-scalable-parallel-2d-fft-for-image-enhancement/). There is also an example in parallella-examples on github (https://github.com/parallella/parallella-examples/tree/master/fft-xcorr).

The structure and the algorithm depends on what your input is and you want to do with it.
