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.

Arttu Ylä-Outinen f7f17a060c Rename pixel_t to kvz_pixel. 2015-07-02 16:58:28 +03:00
Ari Koivula ded6fd9ee8 Renamed typedef pixel to pixel_t. 2015-03-04 16:35:53 +02:00
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 Koivula 669e99dd7f Improve intra SAD AVX2 intrinsics.
- Moved implementations for different sizes to inline functions that are
  defined using each other, reducing the amount of redundant code.

- Performance of sad_8bit_32x32_avx2 improved by about 10% due to unrolling of
  the loop.
