* avcodec/x86/rv34dsp: Remove obsolete MMX functionAndreas Rheinhardt2022-06-221-3/+0
| | | | | | | | | The only systems which benefit from ff_rv34_idct_dc_add_mmx are truely ancient 32bit x86s as all other systems use at least the SSE2 versions (this includes all x64 cpus (which is why this code is restricted to x86-32)).

* x86/rv34dsp: add ff_rv34_idct_dc_add_sse2James Almer2017-02-021-1/+4
| | | | | | | Also disable ff_rv34_idct_dc_add_mmx on x86_64 as the presence of sse2 is guaranteed in such builds. Signed-off-by: James Almer <jamrial@gmail.com>

* Drop DCTELEM typedefDiego Biurrun2013-01-221-3/+3
| | | | | | It does not help as an abstraction and adds dsputil dependencies. Signed-off-by: Ronald S. Bultje <rsbultje@gmail.com>

* x86: Replace checks for CPU extensions and flags by convenience macrosDiego Biurrun2012-09-081-5/+4
| | | | | This separates code relying on inline from that relying on external assembly and fixes instances where the coalesced check was incorrect.

* x86: rename libavutil/x86_cpu.h to libavutil/x86/asm.hMans Rullgard2012-08-091-1/+1
| | | | | | | This puts x86-specific things in the x86/ subdirectory where they belong. Signed-off-by: Mans Rullgard <mans@mansr.com>
* x86: build: replace mmx2 by mmxextDiego Biurrun2012-08-031-1/+1
| | | | | | | Refactoring mmx2/mmxext YASM code with cpuflags will force renames. So switching to a consistent naming scheme beforehand is sensible. The name "mmxext" is more official and widespread and also the name of the CPU flag, as reported e.g. by the Linux kernel.
* rv34dsp x86: implement MMX2 inverse transformChristophe Gisquet2012-04-281-0/+2

* rv34: change most "int stride" into "ptrdiff_t stride".Ronald S. Bultje2012-02-201-2/+2
| | | | | | This prevents having to sign-extend on 64-bit systems with 32-bit ints, such as x86-64. Also fixes crashes on systems where we don't do it and arguments are not in registers, such as Win64 for all weight functions.
* rv34: 1-pass inter MB reconstructionChristophe GISQUET2012-01-161-2/+1
| | | | Implement 1-pass inverse transform and reconstruction for inter blocks.
* rv34: Intra 16x16 handlingChristophe GISQUET2012-01-161-4/+10
| | | | | | | Extract processing of intra 16x16 blocks from intra macroblock processing. Also implement a function performing inverse transform and block reconstruction for DC-only blocks in 1 pass instead of 2.
* rv34: DC-only inverse transformChristophe GISQUET2012-01-121-0/+40
When decoding coefficients, detect whether the block is DC-only, and take advantage of this knowledge to perform DC-only inverse transform. This is achieved by: - first, changing the 108x4 element modulo_three_table into a 108 element table (kind of base4), and accessing each value using mask and shifts. - then, checking low bits for 0 (as they represent the presence of higher frequency coefficients) Also provide x86 SIMD code for the DC-only inverse transform.
