[RFC PATCH v1] arm: kf_bfly4: Introduce ARM neon intrinsics
Hello, This patch introduces ARM NEON Intrinsics to optimize kf_bfly4 routine in celt part of libopus. Using NEON optimized kf_bfly4(_neon) routine helped improve performance of opus_fft_impl function by about 21.4%. The end use case was decoding a music opus ogg file. The end use case saw performance improvement of about 4.47%. This patch has 2 components i. Actua...

[RFC PATCH v1] arm: kf_bfly4: Introduce ARM neon intrinsics
Optimize kf_bfly4 function using ARM NEON intrinsics for SoCs that have NEON VFP unit As initial step, only targetting ARMv7-VFP based SoCs. To enable this optimization, use --enable-armv7-neon-float when running configure command. This is disabled by default. --- Makefile.am | 16 ++++ celt/_kiss_f...
