opus - Mar 2015 - Opus's x86 Optimization

Hello guys
I have profiled opus code(cpu sampling) and identified functions that are
expensive for our use case (mostly x86 silk mode).
Those functions could be optimized for x86 using intrinsics. Looking at source
tree and  there is already optimization work going on ,especially Cisco folks
and Jonathan have already contributed for x86. We would like to have some
optimization  included in future opus releases but certainly we don't want
to duplicate other's effort.
Is there complete list of functions that are going thru optimization process for
future releases?
[I did look at https://wiki.xiph.org/OPUS_TODO but couldn't find info
related to x86 optimization ]
Thanks
Sureshk

Hi Suresh,

Thanks for making me aware of https://wiki.xiph.org/OPUS_TODO

You can find the patches that I (includes Jonathan's patch) queued up
to be picked up by opus at
https://git.linaro.org/people/viswanath.puttagunta/opus.git
Branch: rfcv1_final_armv8

I am currently working mostly on ARM Neon, so can't comment much on x86.

Regards,
Vish

I don't think anyone is actively working on additional x86 optimizations 
at the moment.
