* Resubmit "RGB to YUV conversion using SSE2""hclam@chromium.org2011-02-031-0/+10
| | | | | | | | | | | Introduce SSE2 patch again. BUG=None TEST=None Review URL: http://codereview.chromium.org/6334029 git-svn-id: svn://svn.chromium.org/chrome/trunk/src@73552 0039d316-1c4b-4281-b951-d872f2087c98

| | | | | | | | Reverting patch because ARM build is broken. TBR=ctguil git-svn-id: svn://svn.chromium.org/chrome/trunk/src@73341 0039d316-1c4b-4281-b951-d872f2087c98
* RGB to YUV conversion using SSE2hclam@chromium.org2011-02-011-0/+10
| | | | | | | | | | | | | This code uses SSE2 intrinsics with the feature of 2x2 subsampling for U and V. Performance compared to a pure C version is about 20% faster with better quality.

* Vertical Scaler better pipelined for Atomfbarchard@chromium.org2010-04-231-2/+4
| | | | | | | | | BUG=42064 TEST=sse2 version of scaling should be faster on Atom. No quality change. Review URL: http://codereview.chromium.org/1700010 git-svn-id: svn://svn.chromium.org/chrome/trunk/src@45431 0039d316-1c4b-4281-b951-d872f2087c98

* YUV with clipping.fbarchard@chromium.org2009-05-181-23/+49
| | | | | | | | | | | | All functions do 2 pixels at a time. 90 and 270 rotations implemented. YV16 refactored. YV12 code accepts a YuvType that allows the same code to support YV16 as well. Special case for half size removed. Special case for doubling added. 3.62 ms versus 8.62 for general purpose code.

* YUV conversion code.fbarchard@chromium.org2009-03-061-0/+26
This will be used for reference. Its reasonably simple, fast and high quality. Future versions will be optimized and should try to maintain similar quality. Longer term we may move this to Skia or attempt a hardware version.
