How to use FFT or any other AXI based IP without a processor ?

Hello, I have initialised BRAM with audio signal, Now i want to take FFT of this signal using FFT ip core present in vivado. But i also dont want to use to processor to read data from BRAM and feed to the FFT ip core. What are the other possible ways i can achieve this.
Thanks in anticipation.

@abhinav6 you can probably use this module to interface bram to FFT ip: https://www.xilinx.com/products/intellectual-property/axis_accelerator_adapter.html

You can write some HDL code or use HLS to send the data through the FFT core.

 

Best,

You can use AXI stream and AXI DMA
