George Steed 5c12e0b2de [AArch64] Add SVE2 implementations of HalfFloat{,1}Row ... For HalfFloat1Row, SVE has direct 16-bit integer to half-float conversion instructions so there is no need to widen to 32-bits. For HalfFloatRow, SVE zero-extending loads avoid the need for seperate UXTL(2) instructions. Observed reductions in runtime compared to the existing Neon code: | HalfFloat1Row | HalfFloatRow Cortex-A510 | -38.3% | -17.3% Cortex-A520 | -37.6% | -18.8% Cortex-A720 | -50.1% | -7.8% Cortex-X2 | -50.2% | -0.4% Cortex-X4 | -51.5% | -12.5% Bug: b/42280942 Change-Id: I445071ccd453113144ce42d465ba03c9ee89ec9e Reviewed-on: https://chromium-review.googlesource.com/c/libyuv/libyuv/+/5975319 Reviewed-by: Justin Green <greenjustin@google.com> Reviewed-by: Frank Barchard <fbarchard@chromium.org>		2024-11-07 18:53:00 +00:00
