Multichannel FFT with XADC.


ayhan

Question

Hey all, I have a question about my fft output that is attached. I am dealing with multichannel xadc and multichannel xfft. I have a demux for multichannel xadc which is working at channel sequencer mode,so when the conversion of one channel is done,I read the next channel of adc thanks to demux.I dont have any problem with xadc and its output but the xfft output is really bothering me. I concatenated the outputs of the demux,then the data which is concatenated go through bram which is working as buffer.Then I have another module that connects bram to xfft ip block. The problem is starting from here but I dont know the reason to be honest.Can anyone help me to fix this problem ?image.thumb.png.4ca4c2191abace040ea6c9c7b00d29f1.png
