2014-10-09Rename highbitdepth functions to use highbd prefixDeb Mukherjee
Uses highbd_ prefix convention consistently. Change-Id: I58f7f799a7ff8e32701bcd71c955bcf1cdd4581e
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.

2014-07-10tests: add API_REGISTER_STATE_CHECKJames Zern
used to wrap API functions to ensure full environment consistency as opposed to the renamed ASM_REGISTER_STATE_CHECK which is used with assembly functions. currently checks the FPU tag word in x86/x86_64 gcc builds to ensure emms has been called. Change-Id: Ie241772dbf903d33d516a1add4c8c6783f2e1490
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. It temporarily disables unit test for the SSSE3 version, which showed overflow failure in the new test conditions. Change-Id: I7caf10bba4b6db031add65d8c0eb99426b38aa42

Just making fdct consistent with iht/idct/fht functions which all use stride (# of elements) as input argument. Change-Id: Id623c5113262655fa50f7c9d6cec9a91fcb20bb4

2013-09-05Enable 32x32 Transform unit testJingning Han
This commit enabled a full functional test on 32x32 forward/inverse transform, including round-trip error and memory overflow check. It tests the prototype functions in C and all other implementations if applicable. Change-Id: I9cc50b05abdb4863e7abbcb29209a19b1fe90da7
2013-05-14WIP: 32x32 idct/recon mergeScott LaVarnway
This patch eliminates the intermediate diff buffer usage by combining the short idct and the add residual into one function. The encoder can use the same code as well. Change-Id: I4ea09df0e162591e420d869b7431c2e7f89a8c1a
2013-02-26Enable 32x32 dct testsYaowu Xu
Also 1. Removed the test code for fDCT from the iDCT test. 2. changed the criteria of round trip error to be below 1/block, this is quite strict comparing to smaller transforms when size differences are accounted for. Change-Id: Idb46a6380b04c93fc8e2845c75f5a850366b0090

2012-12-0732x32 transform for superblocks.Ronald S. Bultje
This adds Debargha's DCT/DWT hybrid and a regular 32x32 DCT, and adds code all over the place to wrap that in the bitstream/encoder/decoder/RD. Some implementation notes (these probably need careful review): - token range is extended by 1 bit, since the value range out of this transform is [-16384,16383]. - the coefficients coming out of the FDCT are manually scaled back by 1 bit, or else they won't fit in int16_t (they are 17 bits). Because of this, the RD error scoring does not right-shift the MSE score by two (unlike for 4x4/8x8/16x16). - to compensate for this loss in precision, the quantizer is halved also. This is currently a little hacky. - FDCT and IDCT is double-only right now. Needs a fixed-point impl. - There are no default probabilities for the 32x32 transform yet; I'm simply using the 16x16 luma ones. A future commit will add newly generated probabilities for all transforms. - No ADST version. I don't think we'll add one for this level; if an ADST is desired, transform-size selection can scale back to 16x16 or lower, and use an ADST at that level. Additional notes specific to Debargha's DWT/DCT hybrid: - coefficient scale is different for the top/left 16x16 (DCT-over-DWT) block than for the rest (DWT pixel differences) of the block. Therefore, RD error scoring isn't easily scalable between coefficient and pixel domain. Thus, unfortunately, we need to compute the RD distortion in the pixel domain until we figure out how to scale these appropriately. Change-Id: I00386f20f35d7fabb19aba94c8162f8aee64ef2b
