Pauli Oikkonen ccf683b9b6 Start work on left and right border aware hor_sad
Comes with 4, 8, 16 and 32 pixel wide implementations now, at some point
investigate if this can start to thrash icache

Ari Lemmetti bcabc6fadd Remove pixel blit from strategies. Use memcpy instead. 2016-04-06 18:44:04 +03:00
Ari Koivula 61fc3e87ba Run include-what-you-use fix_includes.py fix_includes.py
The includes should make more sense now and not just happen to compile
due to headers included from other headers.

Used a modified version of IWYU. Modifications were to attribute int8_t
and so on to stdint.h instead of sys/types.h and immintrin.h instead of
more specific headers.

include-what-you-use 0.7 (git:b70df35)
based on clang version 3.9.0 (trunk 264728)

Ari Koivula 8908d85d66 Change all relative includes to absolute 2016-04-01 17:46:44 +03:00
Arttu Ylä-Outinen 864c77f6eb Use kvz_satd_any_size in inter search.
Changes search_frac and kvz_search_cu_iter to use kvz_satd_any_size for
computing the SATDs instead of getting the SATD function with
kvz_pixels_get_satd_func.

Ari Lemmetti 183ee53f47 Add alternative version of rough intra search.
Calculate two costs simultaneously to exploit larger SIMD registers.
Implementation for dual functions missing currently.

Ari Lemmetti 5d96dbc6c0 Make strategy selection use bit depth given via parameter instead of excluding registration with defines 2015-08-12 13:33:38 +03:00
Ari Lemmetti 4122f36089 Prevent the registration of strategies that are incompatible when KVZ_BIT_DEPTH != 8
Remove unnecessary or misleading mentions of "8bit"

Ari Koivula d7383ccb25 Change license to LGPL.
- Everyone who has contributed code to the project has been asked to license
  their contributions under LPGL and they have agreed.

- COPYING file changed to say LGPLv2.1 instead of GPLv2.

- GPL changed to LGPL in the header of every single file that a header and
  header added to the few that were missing one.

- Also.. Happy new year!

Ari Lemmetti 1be2c3aae5 Preparing push to master and misc
-Removed unnecessary <math.h> headers
-Updated AVX/asm optimizations to match the new file hierarchy
-Makefile only compiles .asm files if KVAZAAR_DISABLE_YASM is not set to 1 and TARGET_CPU_ARCH is x86

Ari Koivula a8f7103797 Add AVX2 implementations for sad_8bit_ 8x8, 16x16 and 32x32. 2014-07-18 18:27:30 +03:00
Ari Lemmetti 1e94262f85 Made AVX asm compatible with the changed system
- x86inc.asm is now located in extras
- Removed unused cpu.asm/h

Ari Koivula 5d0df56c94 Move optimizations to their own compilation units according to target.
- This is necessary in order to compile AVX intrinsics correctly in
  Visual Studio. Having everything in their own units should also make
  compiling normal C code with optimizations on easier.

- For now the makefile still relies on GCC __target__ attribute for compiling
  intrinsics.

Ari Koivula 1c97a10a6d Move intra SAD and SATD functions under strategies. 2014-06-16 12:13:41 +03:00
Ari Koivula 1de102be61 Move strategies to their own compilation units.
- Enforces a little bit more hierarchy. Compilation units are in strategies
  and whatever inline includes they have are in a folder with the same name
  as the strategy.
