From 705f5e5e155f6f280a360af220fc5b30cfcee702 Mon Sep 17 00:00:00 2001 From: Janne Grunau Date: Tue, 1 Dec 2015 13:37:41 +0100 Subject: arm64: port synth_filter_float_neon from arm ~25% faster dts decoding overall. The checkasm CPU cycles numbers are not that useful since synth_filter_float() calls FFTContext.imdct_half(). cortex-a57 cortex-a53 synth_filter_float_c: 1866.2 3490.9 synth_filter_float_neon: 915.0 1531.5 With fftc.imdct_half forced to imdct_half_neon: cortex-a57 cortex-a53 synth_filter_float_c: 1718.4 3025.3 synth_filter_float_neon: 926.2 1530.1 --- libavcodec/synth_filter.h | 1 + 1 file changed, 1 insertion(+) (limited to 'libavcodec/synth_filter.h') diff --git a/libavcodec/synth_filter.h b/libavcodec/synth_filter.h index f842c701e3..a93dc4f268 100644 --- a/libavcodec/synth_filter.h +++ b/libavcodec/synth_filter.h @@ -32,6 +32,7 @@ typedef struct SynthFilterContext { } SynthFilterContext; void ff_synth_filter_init(SynthFilterContext *c); +void ff_synth_filter_init_aarch64(SynthFilterContext *c); void ff_synth_filter_init_arm(SynthFilterContext *c); void ff_synth_filter_init_x86(SynthFilterContext *c); -- cgit v1.2.3
