This patch supplies handwritten NEON code for AAC. The benchmarks below were collected by invoking these two commands on each of my boards, A78, A72 and Thinkpad x13s: 1) ./tests/checkasm/checkasm --test=aacencdsp --bench --runs=12 2) ./ffmpeg -y -t 10:00 -f lavfi -i sine /tmp/foo.aac (the first line is speed without the patch, second, with) - A78 abs_pow34_c: 4161.5 ( 1.00x) abs_pow34_neon: 3586.2 ( 1.16x) quant_bands_signed_c: 5548.0 ( 1.00x) quant_bands_signed_neon: 1126.8 ( 4.92x) quant_bands_unsigned_c: 3979.2 ( 1.00x) quant_bands_unsigned_neon: 800.2 ( 4.97x) size= 5251KiB time=00:10:00.00 bitrate= 71.7kbits/s speed=71.6x size= 5251KiB time=00:10:00.00 bitrate= 71.7kbits/s speed=82.3x - A72 abs_pow34_c: 15362.2 ( 1.00x) abs_pow34_neon: 15382.5 ( 1.00x) quant_bands_signed_c: 9926.5 ( 1.00x) quant_bands_signed_neon: 2467.8 ( 4.02x) quant_bands_unsigned_c: 5469.8 ( 1.00x) quant_bands_unsigned_neon: 2089.5 ( 2.62x) size= 5251KiB time=00:10:00.00 bitrate= 71.7kbits/s speed=34.3x size= 5251KiB time=00:10:00.00 bitrate= 71.7kbits/s speed=37.8 - x13s abs_pow34_c: 2413.4 ( 1.00x) abs_pow34_neon: 1796.2 ( 1.34x) quant_bands_signed_c: 2968.9 ( 1.00x) quant_bands_signed_neon: 675.6 ( 4.39x) quant_bands_unsigned_c: 2311.9 ( 1.00x) quant_bands_unsigned_neon: 477.1 ( 4.85x) size= 5251KiB time=00:10:00.00 bitrate= 71.7kbits/s speed= 135x size= 5251KiB time=00:10:00.00 bitrate= 71.7kbits/s speed= 159x Signed-off-by: Martin Storsjö <martin@martin.st> |
