I'm trying to check the performance of in-place and not-in-place FFT.
But it seems I do not check the time right.
I'm running the following code:
void main (void)
printf ("1 Sec=%d\n",Elapsed);
My CPU runs at 2.6GHz so the value of 'Elapsed' should be ~2.6E9
But the value of 'Elapsed' I'm getting is negative.
I'm using Intel Compiler 11.1/064 with IPP 6.1 under RedHat 5.3
Can you help ?
