C-Callable ASM (Cycle Count)

Hi,

I working on TMS320F28069 and I try to estimate the FFT timing.

On the documentation : "C28x Floating Point Unit DSP Library" we found tables with : FFTSize / C-Callable ASM (Cycle Count)

For example, the function RFFT_f32(&rfft) for 1024 FFTSize takes 30357 Cycle Count.

TMS320F28069 have a clock of  90 MHz (11.11-ns Cycle Time).

So I think the timing for the FFT function is:

11.11ns * 30357 = 0.33 ms

Is it correct ??

Thanks.
