* lavu/mem: move the DECLARE_ALIGNED macro family to mem_internal on next+1 bumpAnton Khirnov2021-01-01
| | | | They are not properly namespaced and not intended for public use.
* avcodec/aacsbr_template: Remove pointless runtime initializationAndreas Rheinhardt2020-12-31
| | | | | | | | | | | | | | | | | The sbr_qmf_window_us array is basically symmetric around its middle element and therefore the latter half is currently initialized from the first half at runtime. Yet because the first half is initialized, the array can't be placed in .bss at all, so that one gains nothing from not already initializing the whole array statically. Therefore this commit does exactly this. (There are two exceptions to the symmetry: Elements 384 and 512 are the negations of their mirror element; for the fixed-point decoder, Q31(-x) does not equal -Q31(x). In order to keep the array exactly the same, the latter form has been used for these two elements.) Reviewed-by: Lynne <dev@lynne.ee> Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@gmail.com>

* aacsbr: support hardcoding tables.Reimar Döffinger2014-09-06
| | | | | | | | For sbr_qmf_window_us there is even a question if it maybe should be fully hardcoded all the time. Since half of it is coded, it ends up in .data and not .bss. Signed-off-by: Reimar Döffinger <Reimar.Doeffinger@gmx.de>
* 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>
