and x86-64 only.Expand description
Computes the sum of absolute differences (SADs) of quadruplets of unsigned
8-bit integers in a
compared to those in b
, and stores the 16-bit
results in dst. Eight SADs are performed for each 128-bit lane using one
quadruplet from b
and eight quadruplets from a
. One quadruplet is
selected from b
starting at on the offset specified in imm8
. Eight
quadruplets are formed from sequential 8-bit integers selected from a
starting at the offset specified in imm8
.
