Ari Koivula 947bae24f9 Update Doxygen documentation 
Add module information to all header files.

Update all header file documentations to briefly say what they are, and
to use the javadoc format so the brief actually gets included into the
doxygen documentation.

Remove \file from implementation files, in order to not repeat the info
from the header files.

Add files under strategies and tools to Doxygen and update the Doxygen
settings to be just plain better.

Make README be the main page of Doxygen documentation.

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.
 2015-12-15 11:21:45 +02:00
Arttu Ylä-Outinen 056fa09ba5 Add arbitrary-sized SATD functions.

functions are implemented with macro SATD_ANY_SIZE defined in
strategies-picture.h.

Arttu Ylä-Outinen 728a6abecc Extract macro SATD_NxN.

Arttu Ylä-Outinen 4402e251ae Fix kvz_get_extended_block functions. 
The buffers allocated in functions kvz_get_extended_block_avx2 and
kvz_get_extended_block_generic were too small when the width of the
block was less than its height. Fixed to allocate correctly sized
buffers.

Ari Koivula 0c3c93d456 Optimize intra SAD intrinsics. 
- Added 64x64 version for completeness.
- With the exception of 16x16, these were all slightly slower than the ASM
  versions, as measured by "kvazaar_test -s speed -t intra_sad", but now they
  are on par or slightly faster.
- None of these actually use any AVX2 intrinsics, and probably never will,
  unless someone adds an interface for doing more than one block at a time,
  in which case the non-destructive versions might come in handy.

- The target attributes are not needed anymore due to makefile handling
  targetting now.
- The __attribute__((unused)) used for debugging. I don't know if clang
  supports this attribute or not but it doesn't seem very important so
  I'm removing it just in case.

Ari Lemmetti 2169f9ab8c Added AVX asm comments and fixes 
-Added vzeroupper to satd macro to prevent AVX-SSE transition penalties int picture_x86.asm
-Fixed the order of registers in zero extend macro in picture_x86.asm
-Fixed SATD checkers test pattern in satd_tests.c

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.

Ari Koivula 42295d3cb9 Pass preprocessor defines for supported intrinsics in VS2010 explicitly. 
- _M_IX86_FP defines whether VS should generate code using SSE or SSE2
  instructions. It isn't correct to use it to check whether optional runtime
  optimizations should be compiled in. It's also not defined at all in 64-bit
  mode.

- So let's just keep it simple and give a list of everything that is supported
  as release optimizations. It's not clear from the documentation if all of
  these are really supported. It just list a bunch of intrinsics from these
  that are.

Ari Koivula bd7e021742 Modify strategyselector to work with VS2010. 
- VS doesn't have snprintf.

- VS doesn't support GCC attributes.

- Add defines for __SSE__ and __SSE2__ on VS.
