Hi Jean-Marc and list,
Is the spx_fft function in fftwrap.c a standard fft function?
void spx_fft(void *table, spx_word16_t *in, spx_word16_t *out)
When I say standard, I mean the input "in" is 128 point short data for
the output "out" is 128 short complex value which is stored in 256
short array with real and
image part. Looks like the function did some manipulation on the
output from the kiss_fft. I am
still reading the codes and am not completely understand the code yet.
I am trying to replace
the fft module with some hardware logic. I would greatly appreciate it
if you could clarify my
Thank a lot!
