This makes use of the same approach as the Neon code to avoid redundant narrowing and then widening shifts by instead placing the values at the top portion of the lanes and then shifting down from there instead. Observed reduction in runtime compared to the existing Neon code: Cortex-A510: -41.1% Cortex-A520: -38.2% Cortex-A715: -21.5% Cortex-A720: -21.6% Cortex-X2: -21.6% Cortex-X3: -22.0% Cortex-X4: -23.5% Cortex-X925: -21.7% Bug: b/42280942 Change-Id: Id84872141435566bbf94a4bbf0227554b5b5fb91 Reviewed-on: https://chromium-review.googlesource.com/c/libyuv/libyuv/+/5802966 Reviewed-by: Justin Green <greenjustin@google.com> Reviewed-by: Frank Barchard <fbarchard@chromium.org> |
