I would like to use the HWA to calculate the magnitude of complex ADC samples, length 4096.
SWRU526B, The Radar Hardware Accelerator, says, "The FFT sub-block performs FFT on the incoming 24-bit I and 24-bit Q data stream. The FFT sizes supported are all powers of 2 until 1024 ..."
Should I be concerned that the FFT can only operate on sizes up to 1024? Do I need to use the FFT stitching approach to calculate the magnitude?
I have disabled the interference rejection, windowing, FFT, and LOG2 sub-blocks, so that only the magnitude sub-block on the FFT core computational unit is being used.
Thank you for your help.
