Falk Hüffner	1a02ea65e0	Implement sad8x8 and sad16x16 with pix_abs. Originally committed as revision 1428 to svn://svn.ffmpeg.org/ffmpeg/trunk	22 years ago
Falk Hüffner	3354b0c9e5	Kludge around compilation failure on Alpha. Originally committed as revision 1286 to svn://svn.ffmpeg.org/ffmpeg/trunk	22 years ago
Zdenek Kabelac	af19f78f2f	* using DSPContext - so each codec could use its local (sub)set of CPU extension * these are untested - users/developers please check Originally committed as revision 1197 to svn://svn.ffmpeg.org/ffmpeg/trunk	22 years ago
Falk Hüffner	8b313a4787	Move Alpha optimized IDCT to own file. Based on a patch by Måns Rullgård <mru@users.sourceforge.net>. I've left out the idctCol2 part, because W4 has recently been decreed to be 16383, and also I doubt it will give a noticeable speedup. Originally committed as revision 1029 to svn://svn.ffmpeg.org/ffmpeg/trunk	23 years ago
Falk Hüffner	acd2e05c47	* Fix dct_unquantize_h263_axp for changed block_last_index indexing. * Set qadd to 0 for intra with h263_aic (whatever that may be). Originally committed as revision 1009 to svn://svn.ffmpeg.org/ffmpeg/trunk	23 years ago
Falk Hüffner	6c38306600	Make compilable again after DCT cleanup. It gives wrong results, though, so I disabled it for now. Anybody knows offhand what might be the reason? Originally committed as revision 1005 to svn://svn.ffmpeg.org/ffmpeg/trunk	23 years ago
Falk Hüffner	e447d7d65f	Some nifty stuff for upcoming patches. Originally committed as revision 1004 to svn://svn.ffmpeg.org/ffmpeg/trunk	23 years ago
Falk Hüffner	f9bb4bdffc	Add Alpha assembly for pix_abs16x16. Optimized for pca56, no large win on ev6. Originally committed as revision 979 to svn://svn.ffmpeg.org/ffmpeg/trunk	23 years ago
Falk Hüffner	8c7b533e8b	Synthesize pixels16 functions from pixels functions. Originally committed as revision 942 to svn://svn.ffmpeg.org/ffmpeg/trunk	23 years ago
Falk Hüffner	60286c8a37	Fix for h % 8 == 4 in put_pixels_axp_asm. Originally committed as revision 940 to svn://svn.ffmpeg.org/ffmpeg/trunk	23 years ago
Falk Hüffner	a343d33ed6	Due to version renumbering, Alpha builtins aren't supported in thegcc 3.2 release. Originally committed as revision 937 to svn://svn.ffmpeg.org/ffmpeg/trunk	23 years ago
Falk Hüffner	1c73a3fbf2	Adapt to new 8/16 table scheme. Originally committed as revision 935 to svn://svn.ffmpeg.org/ffmpeg/trunk	23 years ago
Falk Hüffner	57d2bce188	MVI optimizations for motion estimation. Originally committed as revision 831 to svn://svn.ffmpeg.org/ffmpeg/trunk	23 years ago
Falk Hüffner	e3e98d3c23	Remove support for variable BSIZE and INCR, as sub_pixels_* is no longer needed. Originally committed as revision 754 to svn://svn.ffmpeg.org/ffmpeg/trunk	23 years ago
Falk Hüffner	f5abd9fd1a	* Improve xy2 routines slightly * Mark MC pointer arguments as restrict Originally committed as revision 752 to svn://svn.ffmpeg.org/ffmpeg/trunk	23 years ago
Falk Hüffner	0a12d6fdfd	Implement clear_blocks_axp. Originally committed as revision 722 to svn://svn.ffmpeg.org/ffmpeg/trunk	23 years ago
Falk Hüffner	2dbe7ec87c	Make dct_unquantize_h263 work on systems without MVI extension. Originally committed as revision 715 to svn://svn.ffmpeg.org/ffmpeg/trunk	23 years ago
Falk Hüffner	e0580f8c68	Update and activate dct_unquantize_h263_mvi. Thanks to Måns Rullgård for some improvements. Originally committed as revision 714 to svn://svn.ffmpeg.org/ffmpeg/trunk	23 years ago
Falk Hüffner	dde3f77dbc	Use updated motion compensation routines. Originally committed as revision 713 to svn://svn.ffmpeg.org/ffmpeg/trunk	23 years ago
Falk Hüffner	494e409255	Assembly version of put_pixels. This is currently the function that takes the most time, and it allows for more efficient unaligned access and better control over memory latencies. Originally committed as revision 711 to svn://svn.ffmpeg.org/ffmpeg/trunk	23 years ago
Falk Hüffner	d13c54cdc0	Add profiling support. Originally committed as revision 710 to svn://svn.ffmpeg.org/ffmpeg/trunk	23 years ago
Falk Hüffner	bb7d4939ba	Implement put_pixels_clamped and add_pixels_clamped in Assembler. This allows better scheduling of the memory accesses, and is portable among all compilers. Originally committed as revision 709 to svn://svn.ffmpeg.org/ffmpeg/trunk	23 years ago
Falk Hüffner	db42e13bfb	Ugly hack to make the assembler accept MVI instructions. Originally committed as revision 705 to svn://svn.ffmpeg.org/ffmpeg/trunk	23 years ago
Falk Hüffner	b210c96c0c	* Fixed constraints * Support ccc * Support gcc 3.2 builtins Originally committed as revision 704 to svn://svn.ffmpeg.org/ffmpeg/trunk	23 years ago
