2015-06-04vp9_reconintra/d45_predictor: remove temp storageJames Zern

2015-06-04vp9_reconintra: simplify d63_predictorJames Zern
calculate the averages needed for even and odd rows once; this removes a conditional from the inner loop the final average calculated currently relies on above[] being extended, it could be reduced to use above[block_size - 2] + 3 * above[block_size - 1] Change-Id: I70f5eac8d8a2a959c7114844a95826f445c3dd4d

2015-05-13Relocate memory operations for common codeJohann
With the sad functions, and hopefully the variance functions soon, moving to the vpx_dsp location, place the defines used in the reference C code in a common location. Change-Id: I4c8ce7778eb38a0a3ee674d2f1c488eda01cfeca
2015-05-08build_intra_predictors*: reduce above_data sizeJames Zern
currently this needs to be 2x (NEED_ABOVERIGHT) the size of the largest block (32) + 1 (for above_left). reduce the buffer size from 128 + 16 (alignment) to 64 + 16. Change-Id: Idaca1806c7e1214e9437de24e15edc2ebf18f95d
2015-05-07build_intra_predictors*: reduce left_col sizeJames Zern
this should only need to be the size of the largest block, i.e., 32, not 64. Change-Id: Ib8cb2424771fdd2a64c55379597248b2722a5ceb
2015-05-07replace DECLARE_ALIGNED_ARRAY w/DECLARE_ALIGNEDJames Zern
this macro was used inconsistently and only differs in behavior from DECLARE_ALIGNED when an alignment attribute is unavailable. this macro is used with calls to assembly, while generic c-code doesn't rely on it, so in a c-only build without an alignment attribute the code will function as expected.

2015-03-04Declare function used by 'once' with 'void' parametersJohann
Visual Studio is exceptionally picky about this: vp9_reconintra.c(900): warning C4113: 'void (__cdecl *)()' differs in parameter lists from 'void (__cdecl *)(void)' [.build-x86_64-win64-vs10\vpx.vcxproj] Change-Id: I564c7415f4608fd962be8c699d6133a996b545f7
2015-03-03fix a race condition caused by intra function pointer initializationYunqing Wang
This patch fixed webm issue 962. (https://code.google.com/p/webm/issues/detail?id=962) The data races occurred when an encoder and a decoder were created at the same time, and the function pointers were initialized twice. Change-Id: I8851b753c4b4ad4767d6eea781b61f0ac9abb44b

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

2014-05-13Silience -wextra warnings in vp9_reconintra.cJingning Han
The warning messages complained that there are unused arguments in a few prediction modes. This structure was designed on purpose, such that a wrapper function can cover all prediction mode cases and make them readily accessible as an pointer array. This commit silences such warnings.

2013-07-08Make intra prediction pointers RTCD-based.Ronald S. Bultje
This probably has a mildly negative impact on performance, but will (in future commits - or possibly merged with this one) allow SIMD implementations of individual intra prediction functions. We may perhaps want to consider having separate functions per txfm-size also (i.e. 4x4, 8x8, 16x16 and 32x32 intra prediction functions for each intra prediction mode), but I haven't played much with that yet.
