Ronald S. Bultje	235e76aeb8	vp9: initial attempt at a idct_idct_4x4 12bpp x86 simd (sse2) impl. The trouble with this function is that intermediates overflow 31+sign bits, so I've added some helpers (that will also be used in 10/12bpp 8x8, 16x16 and 32x32) to make that easier, basically emulating a half- assed pmaddqd using 2xpmaddwd. It's currently sse2-only, if anyone sees potential in adding ssse3, I'd love to hear it.	10 years ago

Christophe Gisquet	7ece8b50b1	x86: simple_idct: 12bits versions On 12 frames of a 444p 12 bits DNxHR sequence, _put function: C: 78902 decicycles in idct, 262071 runs, 73 skips avx: 32478 decicycles in idct, 262045 runs, 99 skips Difference between the 2: stddev: 0.39 PSNR:104.47 MAXDIFF: 2 This is unavoidable and due to the scale factors used in the x86 version, which cannot match the C ones. In addition, the trick of adding an initial bias to the input of a pass can overflow, as the input coefficients are already 15bits, which is the maximum this function can handle. Overall, however, the omse on 12 bits samples goes from 0.16916 to 0.16883. Reducing rowshift by 1 improves to 0.0908, but causes overflows.

Christophe Gisquet	4369b9dc7b	x86: simple_idct(_put): 10bits versions Modeled from the prores version. Clips to [0;1023] and is bitexact. Bitexactness requires to add offsets in different places compared to prores or C, and makes the function approximately 2% slower. For 16 frames of a DNxHD 4:2:2 10bits test sequence: C: 60861 decicycles in idct, 1048205 runs, 371 skips sse2: 27567 decicycles in idct, 1048216 runs, 360 skips avx: 26272 decicycles in idct, 1048171 runs, 405 skips The add version is not implemented, so the corresponding dsp function is set to NULL to make it clear in a code executing it.

Christophe Gisquet	e652f69b35	x86: simple_idct10_template: fix overflow in pass When the input of a pass has 15 or 16 bits of precision (in particular the column pass), the addition of a bias to W4 may lead to overflows in the input to pmaddwd. This requires postponing the adding of the bias to after the first butterfly. To do so, the fact that m15, unused although zeroed, is exploited. In case the pass is safe, an address can be directly used, and the number of xmm regs can be decreased. Otherwise, the 32bits bias is loaded into it.

Ronald S. Bultje	ce78729033	vp9: don't keep a stack pointer if we don't need it. This saves one register in a few cases on 32bit builds with unaligned stack (e.g. MSVC), making the code slightly easier to maintain. (Can someone please test this on 32bit+msvc and confirm make fate-vp9 and tests/checkasm/checkasm still work after this patch?)	10 years ago

Christophe Gisquet	562ba4a827	blockdsp: remove high bitdepth parameter It is only (mis-)used to set the dsp fucntions clear_block(s). But these functions always work on 16bits-wide elements, which make the parameter useless and actually harmful, as it causes all content on more than 8-bits to not use accelerated functions.
