[opus] [RFC V3 0/8] Ne10 fft fixed and previous
Hi All, Changes from RFC v2 [1] armv7,armv8: Extend fixed fft NE10 optimizations to mdct - Overflow issue fixed by Phil at ARM. Ne10 wip at [2]. Should be upstream soon. - So, re-enabled using fixed fft for mdct_forward which was disabled in RFCv2 armv7,armv8: Optimize fixed point fft using NE10 library - Thanks to Jonathan Lennox, fixed some build fixes on iOS and some copy-paste errors Rest of patches from [1] have no changed. Only minor change is that order in which I applied last 3 patches. You can find my wip opus patches at [3] Ne10 prebuilt libraries for ARMv7 and ARMv8 at [4] for convinience [1]: http://lists.xiph.org/pipermail/opus/2015-May/003015.html [2]: https://git.linaro.org/people/viswanath.puttagunta/Ne10.git/shortlog/refs/heads/fft-fixed [3]: https://git.linaro.org/people/viswanath.puttagunta/opus.git/shortlog/refs/heads/rfcv3_fft_fixed [4]: http://people.linaro.org/~viswanath.puttagunta/opus/NE10_root/ Jonathan Lennox (1): Intrinsics/RTCD related fixes.

[opus] [RFC V3 1/8] armv7(float): Optimize encode usecase using NE10 library
Optimize opus encode (float only) usecase using ARM NE10
library. Mainly effects opus_fft and ctl_mdct_forward
and related functions.
This optimization can be used for ARM CPUs that have NEON
VFP unit. This patch only enables optimizations for ARMv7.
Official ARM NE10 library page available at
http://projectne10.github.io/Ne10/
To enable this optimization, use
--enable-intrinsics --with-NE10=<install_prefix>
or
--enable-intrinsics --with-NE10-libraries=<NE10_lib_dir>
--with-NE10-includes=<NE10_includes_dir>
Compile time checks made during configure process to make sure
optimization option available only when compiler supports NEON
instrinsics.
Runtime checks made to make sure optimized functions only called
on appropriate hardware.

[opus] [RFC V3 2/8] armv7(float): Optimize decode usecase using NE10 library
Optimize opus decode (float only) use case using ARM NE10.
Mainly effects opus_ifft and ctl_mdct_backward and related
functions.
Work based on previous Encode optimization using ARM NE10
library.
TBD: Add commit id of upstream Encode NE10 optimization patch
so that users have reference of how to enable this optimization

[opus] [RFC V3 3/8] Intrinsics/RTCD related fixes. Mostly x86
From: Jonathan Lennox <jonathan at vidyo.com>
* Makes ?enable-intrinsics work with clang and other non-GCC compilers
* Enables RTCD for the floating-point-mode SSE code in Celt.
* Disables use of RTCD in cases where the compiler targets an instruction set by
default.
* Enables the SSE4.1 Silk optimizations that apply to the common parts of Silk
when Opus is built in floating-point mode, not just in fixed-point mode.
* Enables the SSE intrinsics (with RTCD when appropriate) in the Win32 build.
* Fixes a case where GCC would compile SSE2 code as SSE4.1, causing a crash on
non-SSE4.1 CPUs.
* Allows configuration with compilers with non-GCC-flavor flags for enabling
architecture options.
* Hopefully makes the configuration and ifdef?s easier to follow and understand.

[opus] [RFC V3 5/8] aarch64: celt_pitch_xcorr: Fixed point intrinsics
Optimize celt_pitch_xcorr function (for fixed point).
Even though same code in theory should work for ARMv7
as well, turning this on only for aarch64 at the moment since
there is a fixed point asm implementation for ARMv7 neon.

[opus] [RFC V3 7/8] armv7, armv8: Optimize fixed point fft using NE10 library
I'm trying to get these cleaned up and landed, but I'm running into some trouble with this patch. Using commit a08b29d88e3c (July 21) of Ne10, I'm seeing test failures for 60-point FFTs: nfft=60 inverse=0,snr = -3.312408 ** poor snr: -3.312408 ** nfft=60 inverse=1,snr = -16.079597 ** poor snr: -16.079597 ** All other sizes tested appear to work fine (84 to 140 dB of SNR). This doesn't match the results you reported on this list in May, where the FFTs appeared to pass tests, but the MDCTs did not (the latter of which I presume was fixed by the May 12 commits to Ne10). I don't see any commits since then that I would expect to have broken this. Any ideas?
