the all system is alredy built exept the fft.

i read the data from the codec by the audio ip core.

all the samples is stored in the sram and i want to send the samples from the sram to the fft. is it posible?

if i have a good c code of fft i would use it.

and one more question, what will be the best paremetes for the fft core with 1024*8 real samples, fixed point of 24 bit eache.
