* avcodec/x86/sbrdsp: Remove obsolete SSE functionAndreas Rheinhardt2022-06-22
| | | | | | | | | | | x64 always has MMX, MMXEXT, SSE and SSE2 and this means that some functions for MMX, MMXEXT and 3dnow are always overridden by other functions (unless one e.g. explicitly disables SSE2) for x64. So given that the only systems that benefit from ff_sbr_qmf_deint_bfly_sse are truely ancient 32bit x86s it is removed. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>

| | | | | | | | | | | | | | | | | | | | Sandybridge: 47 cycles Having a loop counter is a 7 cycle gain. Unrolling is another 7 cycle gain. Working in reverse scan is another 6 cycles. Signed-off-by: Diego Biurrun <diego@biurrun.de>
* | x86: sbrdsp: force PIC addressing for Win64Christophe Gisquet2013-05-08
| | | | | | | | | | | | MSVC complains about the 32bits addressing, while mingw/gcc does not. Signed-off-by: Michael Niedermayer <michaelni@gmx.at>
* | avcodec/x86/sbrdsp_init: disable using the noise code in x86_64 MSVC, Try #2Michael Niedermayer2013-04-24
| | | | | | | | | | | | | | This should fix building with MSVC until someone can change the code so it works with MSVC Signed-off-by: Michael Niedermayer <michaelni@gmx.at>

* | x86: sbrdsp: implement SSE2 hf_apply_noiseChristophe Gisquet2013-04-19
| | | | | | | | | | | | | | | | | | 233 to 105 cycles on Arrandale and Win64. Replacing the multiplication by s_m[m] by a pand and a pxor with appropriate vectors is slower. Unrolling is a 15 cycles win. A SSE version was 4 cycles slower. Signed-off-by: Michael Niedermayer <michaelni@gmx.at>

|/ | | | | | | | | | | From 312 to 89/68 (sse/sse2) cycles on Arrandale and Win64. Sandybridge: 68/47 cycles. Having a loop counter is a 7 cycle gain. Unrolling is another 7 cycle gain. Working in reverse scan is another 6 cycles. Signed-off-by: Michael Niedermayer <michaelni@gmx.at>

* x86: sbrdsp: Implement SSE qmf_post_shuffleChristophe Gisquet2013-01-06
| | | | | | 255 to 174 cycles on Arrandale / Win64. Unrolling yields no gain. Signed-off-by: Diego Biurrun <diego@biurrun.de>
* x86: sbrdsp: Implement SSE sum64x5Christophe Gisquet2013-01-06
| | | | | | 698 to 174 cycles on Arrandale. Unrolling is a 6 cycles gain. Signed-off-by: Diego Biurrun <diego@biurrun.de>
* SBR DSP x86: implement SSE sbr_hf_genChristophe Gisquet2012-12-07
| | | | | | | | | | | | Start and end index are multiple of 2, therefore guaranteeing aligned access. Also, this allows to generate 4 floats per loop, keeping the alignment all along. Timing: - 32 bits: 326c -> 172c - 64 bits: 323c -> 156c Signed-off-by: Diego Biurrun <diego@biurrun.de>
* x86: Replace checks for CPU extensions and flags by convenience macrosDiego Biurrun2012-09-08
| | | | | This separates code relying on inline from that relying on external assembly and fixes instances where the coalesced check was incorrect.
* SBR DSP x86: implement SSE sbr_hf_g_filtChristophe GISQUET2012-02-23
| | | | | | | | | | | | | | | Unrolling the main loop to process, instead of 4 elements: - 8: minor gain of 2 cycles (not worth the extra object size) - 2: loss of 8 cycles. Assigning STEP to a register is a loss. Output address (Y) is almost always unaligned. Timings: - C (32/64 bits): 117/109 cycles - SSE: 57 cycles Signed-off-by: Ronald S. Bultje <rsbultje@gmail.com>
* SBR DSP x86: implement SSE sbr_sum_square_sseChristophe GISQUET2012-02-23
The 32bits targets have been compiled with -mfpmath=sse for proper reference. sbr_sum_square C /32bits: 82c (unrolled)/102c C /64bits: 69c (unrolled)/82c SSE/32bits: 42c SSE/64bits: 31c Use of SSE4.1 dpps to perform the final sum is slower. Not unrolling to perform 8 operations in a loop yields 10 more cycles. Signed-off-by: Ronald S. Bultje <rsbultje@gmail.com>
