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

I'm considering implementing Opus as the codec for an embedded ARM-based battery powered audio system. In the interest of battery life and board footprint I'd like to specify the smallest CPU that can do the job. In some quick testing on Cortex-A8 (a very different core, but at least ISA compatible and hopefully fairly similar to M4 for things like cycle counts and code size) I saw

First, make sure that OPUS_ARM_INLINE_EDSP (enabling DSP extensions) is defined in your config.h. Also, check for OPUS_ARM_ASM and OPUS_HAVE_RTCD. That means all the asm is enabled. At that point, the best is to run the profiles to see where the CPU time is spent. Cheers, Jean-Marc
