* x86: hpeldsp: implement SSSE3 version of _xy2Christophe Gisquet2014-05-24
| | | | | | | | | | | | | Loading pb_1 rather than pw_8192 was benchmarked to be more efficient. Loading of the 2 yields no advantage. Loading of one saves ~11 cycles. decicycles count: put8: 3223(mmx) -> 2387 avg8: 2863(mmxext) -> 2125 put16: 4356(sse2) -> 3553 avg16: 4481(sse2) -> 3513 Signed-off-by: Michael Niedermayer <michaelni@gmx.at>
* x86: hpeldsp: implement SSE2 put_pixels16_xy2Christophe Gisquet2014-05-24
| | | | | | | | This is obviously equivalent to the avg version, without the avg. 3223(mmx) -> 2006(sse2) Signed-off-by: Michael Niedermayer <michaelni@gmx.at>
* x86: hpeldsp: implement SSE2 versionsChristophe Gisquet2014-05-24
| | | | | | | | | | | | | Those are mostly used in codecs older than H.264, eg MPEG-2. put16 versions: mmx mmx2 sse2 x2: 1888 1185 552 y2: 1778 1092 510 avg16 xy2: 3509(mmx2) -> 2169(sse2) Signed-off-by: Michael Niedermayer <michaelni@gmx.at>
* x86: hpeldsp: avg_pixels_xy2 for mmx2&3dnowChristophe Gisquet2014-05-22
| | | | | | | | | | | This is a port of the inline assembly of the mmx version to use the pavg(us|)b instruction. 8 16 mmx 1498 4355 mmx2 1242 3509 Signed-off-by: Michael Niedermayer <michaelni@gmx.at>
* x86: hpeldsp: mark _xy2 versions as approximateChristophe Gisquet2014-05-22
| | | | | | | | | | Currently, only the mmx version is bitexact, the others (mmxext and 3dnow) are not, in spite of their naming. Therefore, make their name more obvious. Also restore a comment that was removed in 71155d7b. Signed-off-by: Michael Niedermayer <michaelni@gmx.at>

* | avcodec/x86/hpeldsp: fix crash on AMD K6-3+Mikulas Patocka2013-11-03
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | There are instructions pavgb and pavgusb. Both instructions do the same operation but they have different enconding. Pavgb exists in SSE (or MMXEXT) instruction set and pavgusb exists in 3D-NOW instruction set. livavcodec uses the macro PAVGB to select the proper instruction. However, the function avg_pixels8_xy2 doesn't use this macro, it uses pavgb directly. As a consequence, the function avg_pixels8_xy2 crashes on AMD K6-2 and K6-3 processors, because they have pavgusb, but not pavgb. This bug seems to be introduced by commit 71155d7b4157fee44c0d3d0fc1b660ebfb9ccf46, "dsputil: x86: Convert mpeg4 qpel and dsputil avg to yasm" Signed-off-by: Mikulas Patocka <mikulas@artax.karlin.mff.cuni.cz> Signed-off-by: Michael Niedermayer <michaelni@gmx.at>

| | | | | | | | | | This avoids SIMD-optimized functions having to sign-extend their line size argument manually to be able to do pointer arithmetic.
