[AArch64 neon intrinsics v4 0/5] Rework Neon intrinsic code for Aarch64 patchset
Following Tim's comments, here are my reworked patches for the Neon intrinsic function patches of of my Aarch64 patchset, i.e. replacing patches 5-8 of the v2 series. Patches 1-4 and 9-18 of the old series still apply unmodified. The one new (as opposed to changed) patch is the first one in this series, to add named constants for the ARM architecture variants. There are also some minor code

[Aarch64 v2 00/18] Patches to enable Aarch64 (version 2)
As promised, here's a re-send of all my Aarch64 patches, following comments by John Ridges. Note that they actually affect more than just Aarch64 -- other than the ones specifically guarded by AARCH64_NEON defines, the Neon intrinsics all also apply on armv7; and the OPUS_FAST_INT64 patches apply on any 64-bit machine. The patches should largely be independent and independently useful, other

[Aarch64 00/11] Patches to enable Aarch64 (arm64) optimizations, rebased to current master.
Here are my aarch64 patches rebased to the current tip of Opus master. They're largely the same as my previous patch set, with the addition of the final one (the Neon fixed-point implementation of xcorr_kernel). This replaces Viswanath's Neon fixed-point celt_pitch_xcorr, since xcorr_kernel is used in celt_fir and celt_iir as well. These have been tested for correctness under qemu

2 patches related to silk_biquad_alt() optimization
Hi Linfeng, Sorry for the delay -- I was actually trying to think of the best option here. For now, my preference would be to keep things bit-exact, but should there be more similar optimizations relying on 64-bit multiplication results, then we could consider having a special option to enable those (even in C).

[PATCH 8/8] Optimize silk_NSQ_del_dec() for ARM NEON
Created corresponding unit test, and the optimization is bit exact with C function. This optimization speeds up SILK encoder on NEON as following. Fixed-point: Complexity 0-5: 0% Complexity 6-7: 6% Complexity 8-9: 10% Complexity 10: 8% Got similar results on floating-point. --- silk/NSQ_del_dec.c | 6 +- silk/SigProc_FIX.h | 4
