Justin Ruggles	0e8fdd41c2	dsputil: use cpuflags in x86 emu_edge_core avoids passing around the extra argument among all the macros it uses	13 years ago
Justin Ruggles	395f2e70dd	dsputil: use movups instead of movdqu in ff_emu_edge_core_sse() This allows emulated_edge_mc_sse() and gmc_sse() to be used under AV_CPU_FLAG_SSE.	13 years ago
Justin Ruggles	9d06037d48	twinvq: add SSE/AVX optimized sum/difference stereo interleaving	13 years ago
Justin Ruggles	b8f02f5b4e	dsputil: use cpuflags in x86 versions of vector_clip_int32()	13 years ago
Justin Ruggles	4e8e262476	fmtconvert: port int32_to_float_fmul_scalar() x86 inline asm to yasm	13 years ago
Ronald S. Bultje	38e06c2969	Move clipd macros to x86util.asm. This allows sharing them between multiple .asm files.	14 years ago
Dave Yeo	cc73511e8e	Fix NASM include directive Signed-off-by: Ronald S. Bultje <rsbultje@gmail.com>	14 years ago
Ronald S. Bultje	3a39195b1d	Move x86inc.asm to libavutil/. This allows using it in libswscale/ also.	14 years ago
Justin Ruggles	6054cd25b4	ac3enc: add int32_t array clipping function to DSPUtil, including x86 versions.	14 years ago
Dave Yeo	d69f9a4234	Add support for a.out object format to assembler macros. This format is still used by e.g. OS/2. Signed-off-by: Diego Biurrun <diego@biurrun.de>	14 years ago
Diego Biurrun	888fa31eca	Fix FSF address copy paste error in some license headers.	14 years ago
Justin Ruggles	e6e9823488	Add apply_window_int16() to DSPContext with x86-optimized versions and use it in the ac3_fixed encoder.	14 years ago
Mans Rullgard	2912e87a6c	Replace FFmpeg with Libav in licence headers Signed-off-by: Mans Rullgard <mans@mansr.com>	14 years ago
Ronald S. Bultje	17cf7c68ed	Fix ff_emu_edge_core_sse() on Win64. Fix emu_edge_v_extend_15 to be <128 bytes on Win64, by being more strict on the size of registers and which registers are being used for operations where multiple are available. This fixes segfaults in emulated_edge() function calls on Win64.	14 years ago
Justin Ruggles	c73d99e672	Separate format conversion DSP functions from DSPContext. This will be beneficial for use with the audio conversion API without requiring it to depend on all of dsputil. Signed-off-by: Mans Rullgard <mans@mansr.com>	14 years ago
Ronald S. Bultje	81f2a3f4ff	Implement a SIMD version of emulated_edge_mc() for x86. From ~550 cycles (C version) to 170 (SSE/x86-64), 206 (MMX/x86-32) and 196 (SSE2/x86-32) cycles.	14 years ago
Jason Garrett-Glaser	2966cc1849	Update x264asm header files to latest versions. Modify the asm accordingly. GLOBAL is now no longoer necessary for PIC-compliant loads. Originally committed as revision 23739 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Alex Converse	3deb53849e	Implement an sse version of scalarproduct_float(). Originally committed as revision 21386 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Loren Merritt	758c7455f1	fix a crash in ape decoding on x86_32 sse2 Originally committed as revision 20777 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Loren Merritt	a4605efdf5	slightly faster scalarproduct_and_madd_int16_ssse3 on penryn, no change on conroe Originally committed as revision 20743 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Loren Merritt	b1159ad928	refactor and optimize scalarproduct 29-105% faster apply_filter, 6-90% faster ape decoding on core2 (Any x86 other than core2 probably gets much less, since this is mostly due to ssse3 cachesplit avoidance and I haven't written the full gamut of other cachesplit modes.) 9-123% faster ape decoding on G4. Originally committed as revision 20739 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Loren Merritt	b10fa1bb8b	port ape dsp functions from sse2 to mmx now requires yasm Originally committed as revision 20722 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Loren Merritt	b07781b6e4	fix linking on systems with a function name prefix (10l in r20287) Originally committed as revision 20294 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Loren Merritt	e17ccf60fe	huffyuv: add some const qualifiers Originally committed as revision 20290 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Loren Merritt	2f77923d72	simd add_hfyu_left_prediction 2.2x faster than C on conroe, 3.6x on penryn. 4-6% faster huffyuv decoding if using left or plane mode and yuv Originally committed as revision 20287 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Loren Merritt	3daa434a40	ff_add_hfyu_median_prediction_mmx2 overall ffvhuff decoding speedup: 28% on core2, 25% on k8. Originally committed as revision 17059 to svn://svn.ffmpeg.org/ffmpeg/trunk	16 years ago
Diego Biurrun	a6493a8fbd	Rename libavcodec/i386/ --> libavcodec/x86/. It contains optimizations that are not specific to i386 and libavutil uses this naming scheme already. Originally committed as revision 16270 to svn://svn.ffmpeg.org/ffmpeg/trunk	16 years ago
Jason Garrett-Glaser	40c7d0ae3c	Add automatic prefix handling to yasm functions. Does nothing now, but will be useful for porting x264 asm in the future. Originally committed as revision 16234 to svn://svn.ffmpeg.org/ffmpeg/trunk	16 years ago
Loren Merritt	7ca7d5fae0	file which should have been added in r14749 Originally committed as revision 14751 to svn://svn.ffmpeg.org/ffmpeg/trunk	17 years ago
