James Almer	74a87ae210	x86/vp9itxfm: fix register clobbering in ff_vp9_idct_idct_4x4_add_12_sse2 ... Reviewed-by: Henrik Gramner <henrik@gramner.com> Signed-off-by: James Almer <jamrial@gmail.com>	10 years ago
Ronald S. Bultje	e578638382	vp9: use registers for constant loading where possible.	10 years ago
Ronald S. Bultje	408bb8556f	vp9: refactor itx coefficients and share between 8 and 10/12bpp.	10 years ago
Ronald S. Bultje	eb4b5ff738	vp9: add itxfm_add eob shortcuts to 10/12bpp functions. ... These aren't quite as helpful as the ones in 8bpp, since over there, we can use pmulhrsw, but here the coefficients have too many bits to be able to take advantage of pmulhrsw. However, we can still skip cols for which all coefs are 0, and instead just zero the input data for the row itx. This helps a few % on overall decoding speed.	10 years ago

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
