George Steed 61bdaee13a Add Neon I8MM implementations of ARGB to UV and variants ... The maximum coefficient is 128, so store constants negated to take advantage of -128 being representable in 8-bit integers. This allows us to use the I8MM USDOT instructions. Reduction in time taken observed compared to the existing Neon implementation, as a geomean of all ARGBToUV variants: Cortex-A510: -7.1% Cortex-A520: -2.1% Cortex-A710: -8.4% Cortex-A715: -0.3% Cortex-A720: -0.3% Cortex-X2: -40.0% Cortex-X3: -43.3% Cortex-X4: -11.3% Cortex-X925: -2.5% Change-Id: Id06dc17d101b66975b84b93e5abe91c0032921dd Reviewed-on: https://chromium-review.googlesource.com/c/libyuv/libyuv/+/6535686 Reviewed-by: Frank Barchard <fbarchard@chromium.org> Reviewed-by: Justin Green <greenjustin@google.com> Commit-Queue: Frank Barchard <fbarchard@chromium.org>		2025-05-12 11:14:00 -07:00
