Christophe Gisquet	74c414202f	x86: simple_idct10_template: use const This avoid going through constants.c while still sharing them with proresdsp.asm Reviewed-by: "Ronald S. Bultje" <rsbultje@gmail.com> Signed-off-by: Michael Niedermayer <michael@niedermayer.cc>	9 years ago
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.

Christophe Gisquet	e9a68b0316	x86: prores: templatize 10 bits simple_idct This should be reused for a generic simple_idct10 function. Requires a bit of trickery to declare common constants in C. Signed-off-by: Michael Niedermayer <michael@niedermayer.cc>	9 years ago
