Hello!

Question from customer: How to reach performance of 34.5us for 1024 Point Complex FFT using the ADSP-21479? Is there any code example or library available?

Customer's calculations (based on ADSP-214xx_HRM_rev0.3) shows that 39168 cycles (294.5us) are requred for 1024 pint FFT on signal lengths with power of 2.

 

Thanks,

Aleksey
