Thank Jean-Mark and Jonathan! I tested current OPUS encoder in floating-point with Complexity 8. Hacking using the attached patch (which will generate "#define OPUS_ARM_MAY_HAVE_NEON 1" in config.h) will speed up about 14.7% on my Chromebook. Probably it's because many NEON intrinsics optimizations can benefit both fixed-point and floating-point encoder. So if it's safe enough to enable MAY_HAVE_NEON in floating-point by default, it could speed up floating-point N...

Semantically, OPUS_ARM_MAY_HAVE_NEON is supposed to mean the compiler supports, and the CPU may support, Neon assembly code, which isn’t necessarily the same thing as the compiler supporting Neon intrinsics. (The Visual Studio ARM compiler, for instance, supports intrinsics but not assembly.) So I don’t think this patch is the right...

...should be expected? What I really want to know is if Opus could potentially run faster than Vorbis for equivalent audio. I also must mention I am cross compiling with a different build system. I have attempted different sets of compilation defines. Latest run included the following: OPUS_ARM_ASM OPUS_ARM_MAY_HAVE_NEON OPUS_ARM_MAY_HAVE_MEDIA OPUS_ARM_INLINE_EDSP OPUS_ARM_INLINE_NEON OPUS_ARM_INLINE_ASM FIXED_POINT OPUS_BUILD HAVE_LRINT HAVE_LRINTF Thanks!

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

This sequence of patches provides arm64 support for Opus. Tested on iOS, Android, and Ubuntu 14.04. The patch sequence was written on top of Viswanath Puttagunta's Ne10 patches, but all but the second ("Reorganize pitch_arm.h") should, I think, apply independently of it. It does depends on my previous intrinsics configury reorganization, however. Comments welcome. With this and

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
