George Steed 899bc48327 [AArch64] Add SVE2 implementations of ARGBTo{RAW,RGB24}Row ... There is no nice way of forming the TBL permute indices here since we are operating on sets of three bytes at a time, so instead load the appropriate indices from a static array. We can make use of SVE predication to ensure we are operating on a multiple of three bytes for the load/store instructions rather than needing to make use of more expensive LD4 or ST3 instructions. Reduction in runtime observed compared to the existing Neon implementations: | ARGBToRAWRow | ARGBToRGB24Row Cortex-A510 | -50.8% | -19.9% Cortex-A720 | -39.8% | -39.1% Cortex-X2 | -66.5% | -51.9% Bug: libyuv:973 Change-Id: Iaead678715a3d70d54cf823391272a6196836769 Reviewed-on: https://chromium-review.googlesource.com/c/libyuv/libyuv/+/5631544 Reviewed-by: Justin Green <greenjustin@google.com> Reviewed-by: Frank Barchard <fbarchard@chromium.org>		2024-07-08 20:27:54 +00:00
