2014-12-02Added high bitdepth sse2 transform functionsPeter de Rivaz
Also removes some spurious changes in common/vp9_blockd.h which was introduced by a rebase issue between nextgen and master branches. Change-Id: If359f0e9a71bca9c2ba685a87a355873536bb282 (cherry picked from commit 005d80cd05269a299cd2f7ddbc3d4d8b791aebba) (cherry picked from commit 08d2f548007fd8d6fd41da8ef7fdb488b6485af3) (cherry picked from commit 4230c2306c194c058f56433a5275aa02a2e71d56)

Bit-stream clarification related to Issue 868. Change-Id: I92a7bc5b7782c9ea5c3f6cceec761742183c9514
2014-10-03Incorporate WRAPLOW macro into non-highbitdepth txDeb Mukherjee
Incorporates the WRAPLOW macro into the non-highbitdepth transforms to aid hardware verification between a software C model and an intended hardware implementation though the use of the configure options: --enable-experimental --enable-emulate-hardware. Note that to avoid further discrepancies between the sse/sse2 implementations of the transforms and the C implementation, when the emulate hardware option is invoked, we also disable sse/sse2/etc. Also incudes some minor cleanups/renaming etc. Change-Id: Ib864d8493313927d429cce402982f1c8e45b3287
2014-09-11Adds high bitdepth transform functions and testsDeb Mukherjee
Adds various high bitdepth transform functions and tests. Much of the changes are related to using typedefs tran_low_t and tran_high_t for the final transform cofficients and intermediate stages of the transform computation respectively rather than fixed types int16_t/int. When vp9_highbitdepth configure flag is off, these map tp int16_t/int32_t, but when the flag is on, they map to int32_t/int64_t to make space for needed extra precision.

2014-06-03Rework unit test for 8x8 transformationJingning Han
This commit reworks the unit test for 8x8 forward/inverse transformation. It adds extreme input value test to detect overflow issues in the intermediate steps.

2012-08-07A bit of temporary relief on encoder slownessYaowu Xu
The commit replaces run-time initialization of cosine constants with static constant values, which provides ~30% relief on slow speed.
