Martin Storsjö 70db14376c swscale: aarch64: Optimize the final summation in the hscale routine ... Before: Cortex A53 A72 A73 Graviton 2 Graviton 3 hscale_8_to_15_width8_neon: 8273.0 4602.5 4289.5 2429.7 1629.1 hscale_8_to_15_width16_neon: 12405.7 6803.0 6359.0 3549.0 2378.4 hscale_8_to_15_width32_neon: 21258.7 11491.7 11469.2 5797.2 3919.6 hscale_8_to_15_width40_neon: 25652.0 14173.7 12488.2 6893.5 4810.4 After: hscale_8_to_15_width8_neon: 7633.0 3981.5 3350.2 1980.7 1261.1 hscale_8_to_15_width16_neon: 11666.7 5951.0 5512.0 3080.7 2131.4 hscale_8_to_15_width32_neon: 20900.7 10733.2 9481.7 5275.2 3862.1 hscale_8_to_15_width40_neon: 24826.0 13536.2 11502.0 6397.2 4731.9 Thus, this gives overall a 8-29% speedup for the smaller filter sizes, around 1-8% for the larger filter sizes.
