Hello, I received feedback from engineers working on NE10 [1] that it would be better to use NE10 [1] for FFT optimizations for opus use cases. However, these FFT patches are currently in review and haven't been integrated into NE10 yet. While the FFT functions in NE10 are getting baked, I wanted to optimize the celt_pitch_xcorr (floating point only) and use it to introduce ARM NEON

...e that. I wrote a simple patch demonstrating this (attached... it applies on top of your full series, so it'd be a little work to rebase it into place here). It adds one 16-byte table and 16 instructions, and even gives speed-ups on non-NEON CPUs by reusing the existing EDSP asm. Testing on comp48-stereo.sw encoded to 64 kbps and decoded with a 15% loss rate on a Novena using opus_demo (by using RTCD and changing the function pointers to the version of the code to test), optimizing xcorr_kernel gives almost as much speed-up as intrinsics for all of celt_fir: celt_fir_c, xcorr_kernel_c:...

...y into opus. You can view my opus wip code at [2]. Note that while I found some issues both with the NE10 library(fixed fft) and with Linaro toolchain (armv8 intrinsics), the work related to opus is complete, meaning that these patches are functional and I am able to successfully encode and decode comp48-stereo.sw [4] using commands ./opus_demo -e restricted-lowdelay 48000 2 96000 comp48-stereo.sw xcorr.opus ./opus_demo -d 48000 2 xcorr.opus <output> and able to hear the audio clearly. Below are some issues *OUTSIDE* opus project I discovered: - Issues with Linaro Toolchain 14.11 (based on g...

I rebased my previous 3 patches to the current master with minor changes. Patches 1 to 3 replace all my previous submitted patches. Patches 4 and 5 are new. Thanks, Linfeng Zhang
