TS-Lib - Cache Aware FFT Profile

The table below illustrates complex FFT profiles in seconds:

Sizes ez_c2cfft_f ez_ci2cfft_f ez_c2cfft_f ez_ci2cfft_f
512 7.180e-06 7.180e-06 7.173e-06 7.173e-06
1k 1.573e-06 1.573e-06 1.572e-06 1.572e-06
2k 3.491e-05 3.491e-05 3.467e-05 3.467e-05
4k 1.275e-04 1.275e-04 1.276e-04 1.276e-04
8k 2.777e-04 2.777e-04 2.785e-04 2.785e-04
16k 6.042e-04 6.042e-04 6.032e-04 6.032e-04

16k complex FFT = 604 s

* Profiles are calculated from an average of 0x1000 iterations on a T2PC 600 MHz rev 3
  board with TigerSharc TS201 rev 2.0 silicon.
