Diego Biurrun	01621202aa	build: miscellaneous cosmetics Restore alphabetical order in lists, break overly long lines, do some prettyprinting, add some explanatory section comments, group parts together that belong together logically.	10 years ago
Diego Biurrun	1a094af638	fft: Split MDCT bits off from FFT	10 years ago
Janne Grunau	a0fc780a20	arm64: int32_to_float_fmul neon asm 3% faster dts decoding on a cortex-a57. cortex-a57 cortex-a53 int32_to_float_fmul_array8_c: 1270.9 4475.6 int32_to_float_fmul_array8_neon: 328.6 569.2 int32_to_float_fmul_scalar_c: 928.5 4119.6 int32_to_float_fmul_scalar_neon: 309.1 524.1	10 years ago
Janne Grunau	705f5e5e15	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	10 years ago
Janne Grunau	c33c1fa8af	arm64: convert dcadsp neon asm from arm ~2% faster dts decoding overall. cortex-a57 cortex-a53 dca_decode_hf_c: 474.8 1659.9 dca_decode_hf_neon: 225.2 301.1 dca_lfe_fir0_c: 913.2 1537.7 dca_lfe_fir0_neon: 286.8 451.9 dca_lfe_fir1_c: 848.7 1711.5 dca_lfe_fir1_neon: 387.1 506.4	10 years ago

Diego Biurrun	3d5d46233c	opus: Factor out imdct15 into a standalone component It will be reused by the AAC decoder.	11 years ago
Janne Grunau	d3f5b94762	aarch64: opus NEON iMDCT and FFT Opus celt decoding 11% faster and the iMDCT over 2.5 times faster on Apple's A7.	12 years ago
Janne Grunau	3956a5e0ea	aarch64: NEON vorbis_inverse_coupling From the ARMv7 NEON version. 16 times faster as the C version, overall more than 12% faster vorbis decoding on Apple's A7.	12 years ago
Janne Grunau	8f9fe6ae34	aarch64: NEON fixed/floating point MPADSP apply_window 30%/25% (fixed/float) faster mp3 decoding on Apple's A7. The floating point decoder is approximately 7% faster.	12 years ago
Janne Grunau	ee2bc5974f	aarch64: NEON float (i)MDCT Approximately as fast as the ARM NEON version on Apple's A7.	12 years ago
Janne Grunau	650c4300d9	aarch64: NEON float FFT Approximately as fast as the ARM NEON version on Apple's A7.	12 years ago
Janne Grunau	d3789eeeed	aarch64: implement videodsp.prefetch 8% faster h264 decoding on Apple A7.	12 years ago
Diego Biurrun	0e083d7e43	build: Group general components separate from de/encoders in arch Makefiles This is in line with how the top-level libavcodec Makefile is structured.	12 years ago
Janne Grunau	fe96769bed	aarch64: port neon clobber test from arm	12 years ago
Janne Grunau	36e3b1f2fd	aarch64: h264 loop filter NEON optimizations Ported from ARMv7 NEON.	12 years ago
Janne Grunau	c65d67ef50	aarch64: hpeldsp NEON optimizations Ported from ARMv7 NEON.	12 years ago
Janne Grunau	d5dd8c7bf0	aarch64: h264 qpel NEON optimizations Ported from ARMv7 NEON.	12 years ago
Janne Grunau	8438b3f09f	aarch64: h264 idct NEON assembler optimizations Ported from ARMv7 NEON.	12 years ago
Janne Grunau	71617884a2	aarch64: h264 chroma motion compensation NEON optimizations Since RV40 and VC-1 use almost the same algorithm so optimizations for those two decoders are easy to do and included.	12 years ago
