We are using a DaVinci in the FLEX-6000 which is a Sitara with the C674X
processor. Before we switched to doing all of the baseband FFTs in the
C674x, we used FFTW for prototyping. It did detect and use the NEON just
fine. The ARM is a Cortex-A8 and exactly the same processor/die as the
Sitara.

Oops. I mean the Tiva C, not the Sitara.

Hello,
There is also scope for reducing CPU load through algorithm
modifications. For example the post filter uses a bunch of FFTs but
could be implemented more efficiently in the time domain. It would be
effectively the same signal processing, just implemented differently.

Hi Frank,
LibAV and FFTW both have support for NEON extensions. It would be
interesting to benchmark their FFT against what we're using now.
That could be a quick validation regarding whether NEON is helpful.
Both the softmodem and the codec can use accelleration.
Hi list,
I would just like to chime in with some observations I have made in the
embedded industry lately,
where it seems like any die shrink to 28nm for ARM usually goes hand in hand
with a move to the Cortex series of cores. The Cortex cores usually have SIMD
(NEON) acceleration as well as (a
