Janne Grunau	98fdfa9970	ppc: reduce overreads when loading 8 pixels in altivec dsp functions Altivec can only load naturally aligned vectors. To handle possibly unaligned data a second vector is loaded from an offset of the original location and the data is recovered through a vector permutation. Overreads are minimal if the offset for second load points to the last element of data. This is 7 for loading eight 8-bit pixels and overreads are reduced from 16 bytes to 8 bytes if the pixels are 64-bit aligned. For unaligned pixels the overread is reduced from 23 bytes to 15 bytes in the worst case.	11 years ago

Kostya Shishkov	f399e406af	altivec: perform an explicit unaligned load Implicit vector loads on POWER7 hardware can use the VSX instruction set instead of classic Altivec/VMX. Let's force a VMX load in this case. Signed-off-by: Martin Storsjö <martin@martin.st>	11 years ago

Ronald S. Bultje	015821229f	vp3: Use full transpose for all IDCTs This way, the special IDCT permutations are no longer needed. This is similar to how H264 does it, and removes the dsputil dependency imposed by the scantable code. Also remove the unused type == 0 cases from the plain C version of the idct.

Bultje	62844c3fd6	h264: Integrate clear_blocks calls with IDCT The non-intra-pcm branch in hl_decode_mb (simple, 8bpp) goes from 700 to 672 cycles, and the complete loop of decode_mb_cabac and hl_decode_mb (in the decode_slice loop) goes from 1759 to 1733 cycles on the clip tested (cathedral), i.e. almost 30 cycles per mb faster.
