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.

2013-10-10SSE2 8-tap sub-pixel filter optimizationYunqing Wang
To ensure fast encoding/decoding on devices without ssse3 support, SSE2 optimization of sub-pixel filters was done. Test using 1080p clip showed the decoder speeds were ~70fps with ssse3 filters, ~60fps with sse2 filters, and ~15fps with c filters. Change-Id: Ie2088f87d83a889fba80a613e4d0e287aadd785c

2013-08-30Fix intermediate height in convolve_cTero Rintaluoma
- Intermediate height was not correct i.e. when block size is 4 and y_step_q4 is 6. In this case intermediate height was (4*6) >> 4 = 1 and vertical interpolation needs two source pixels plus 7 extra pixels for taps. - Also if the current output block is 16x16 and we are using 4x upscaling we need only 12 rows after horizontal filtering instead of 16. Patch Set 2: Intermediate_height updated after CL 66723 "Fix bug in convolution functions (filter selection)" Change-Id: I5a1a1bc2ac9d5edb3a6e0818de618bf318fdd589
2013-08-23Fix bug in convolution functions (filter selection)Adrian Grange
(In response to Issue 604: https://code.google.com/p/webm/issues/detail?id=604) There were bugs in the convolution code for two cases: 1. Where the filter table was assumed to be aligned to a 256 byte boundary. The offset of the pixel in the source buffer was computed incorrectly. 2. Where no such alignment assumption was made. An incorrect address for the filter table base was used. To fix both problems, I now assume that the filter table is 256-byte aligned and modify the pixel offset calculation to match. A later patch should remove the restriction that the filter table is aligned to a 256-byte boundary. There was also a bug in the ConvolveTest unit test (convolve_test.cc). (Bug & initial fix suggestion submitted by Tero Rintaluoma and Sami Pietilä). Change-Id: I71985551e62846e55e40de9e7e3959d4805baa82

Call the individually optimized horizontal and vertical functions. This implementation abuses the temp buffer. This will be replaced with a custom optimized function. Over 2x speedup. Change-Id: I5b908d2a73d264e9810d6022bbff73207a3055dd

2013-04-18convolve: support larger blocks, fix asm saturation bugJohn Koleszar
Updates the common convoloution code to support blocks larger than 16x16, and rectangular blocks. This uncovered a bug in the SSSE3 filtering routines due to the order of application of saturation. This commit fixes that bug, adjusts the unit test to bias its random values towards the extremes, and adds a test to ensure that all filters conform to the expected pairwise addition structure.

2013-02-27convolve test: validate 1D filters are 1DJohn Koleszar
Since the 8-tap lowpass filter is non-interpolating, the results are different between applying it at whole-pel values and not. This means that 1D-only versions are requried to be implemented, as opposed to being an optimization of the 2D case. Calling the 2D filter instead of the horizontal-only filter is not equivalent in this case. Update the test to pass invalid filters to the unused stage of the 1D-only calls, to verify they're unused. Change-Id: Idc1c490f059adadd4cc80dbe770c1ccefe628b0a
2013-02-27Run all filters through convolve testJohn Koleszar
Updates the convolve test to verify that all filters match the reference implementation. This verifies commit 30f866f, which fixed some problems with the SSE3 version of the filters for the vp9_sub_pel_filters_8s and vp9_sub_pel_filters_8lp banks due to overflow and order of operations.

2013-02-27Use 256-byte aligned filter tablesJohn Koleszar
This avoids duplicating all the filters twice. Includes fixups to the convolve routines and associated tests to make this work. Change-Id: I922f86021594e55072ddb63b42b2313605db6e00
2013-02-26Refactor inter recon functions to support scalingJohn Koleszar
Ensure that all inter prediction goes through a common code path that takes scaling into account. Removes a bunch of duplicate 1st/2nd predictor code. Also introduces a 16x8 mode for 8x8 MVs, similar to the 8x4 trick we were doing before. This has an unexpected effect with EIGHTTAP_SMOOTH, so it's disabled in that case for now.

2013-02-08Restore SSSE3 subpixel filters in new convolve frameworkJohn Koleszar
This commit adds the 8 tap SSSE3 subpixel filters back into the code underneath the convolve API. The C code is still called for 4x4 blocks, as well as compound prediction modes. This restores the encode performance to be within about 8% of the baseline. Change-Id: Ife0d81477075ae33c05b53c65003951efdc8b09c
2013-02-05Add 8-tap generic convolverJohn Koleszar
This commit introduces a new convolution function which will be used to replace the existing subpixel interpolation functions. It is much the same as the existing functions, but allows for changing the filter kernel on a per-pixel basis, and doesn't bake in knowledge of the filter to be applied or the size of the resulting block into the function name. Replacing the existing subpel filters will come in a later commit. Change-Id: Ic9a5615f2f456cb77f96741856fc650d6d78bb91
