I want a fft ip for fpga, who can tell me what to do this?

Hello!

I found that in some future there should be FPGA FFT example on the IPNet.

Can someone tell me when should I expect that? I need FFT procedure that would be able to give about 2048 points spectrum at 10kHz sampling rate (FFT value every 5 Hz)

Can you tell us more of the application?  Also why is it not possible to do the FFT on the RT controller (cRIO) or PXI (if R series board).  Do you need all the bins, or just specific ones?

Hi,
The FPGA IP is now available

Unfortunately there are neither details on how many channels one could simultaneously FFT on either the PXI 7831R or the PXI 7833R nor the expected time needed to execute a 1024/2048 point FFT of 16 bit data
