Is there existing examples for a 64 K point FFT for the ADSP-21857?
I have a typo in the question. The part is ADSP-21587.
Hi Belenie, I tested the attached 64K point FFT (magnitude squared) code with the FFT accelerator API "accel_rfft_large_mag_sq" on ADSP-SC589 EZ-Kit. Please find the same attached. Also attaching the matlab script which I used to generate the test data consisting of two sine waves of frequencies 4K Hz and 8K Hz. Also attaching a screenshot of the plotted FFT (magnitude squared) output. Thanks, Mitesh
