Output format of FFT IP core

I am trying to output the results of FFT IP core to my PC. I need to convert the FFT results to decimal format. Our output setup of the FFT is fixed point, 25bit data output width, natural order, and 4096 length. I need the help to convert the outputs into decimal format. Thanks! HD

    Hi,

    As I understand it, you are trying to convert the FFT output to decimal. As I look into the FFT user guide, seems like there is no specific feature to output data in decimal format. Sorry for the inconvenience. You might need to look into coding conversion logic of your own to perform the conversion.

    Please let me know if there is any concern. Thank you.

    Best regards,
