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
