FFT with FMCOMMS2

Hi,

 

I am new to Zynq and FPGA programming so any advice is greatly appreciated.

 

I intend to FFT the signal from the receive path from AD9361, here are some of my queries:

 

1) If I want to FFT the receive signal, do I place the FFT IP block after the "AD9361 adc dma"? Is there any documentation on this "AD9361 adc dma" IP?

2) Is this "AD9361 adc dma" a actual DMA, or is it just a controller interfacing with another DMA?

3) How do I connect the "AD9361 adc dma" ports to the "AXI FFT" block? Do I need to instantiate another DMA block after "AD9361 adc dma" block and use this new DMA block to connect to the "AXI FFT"?

 

Thanks!
