Implement FFT in parallel

Hello, I have a question about the implementation of FFT in parallel. In the system, I have one main clock, let's call it Fsys. I have several data streams, with a lower rate than Fsys. S...

Hi All,

Does anyone know how to perform FFT using some FFT size and combine after completed all the chunk of data rather than using on big FFT size inside FPGA? For example, compute 32k FFT using 8192 FFT size with repeating 4x using the same 8k FFT? The reason to do this is to reutilized the FFT logic inside the FPGa in order to save logic consumption.
