Expand description
Compute the sum of absolute differences of quadruplets of unsigned
8-bit integers in left
and right
, and store the 16-bit results
in right
. Quadruplets are selected from left
and right
with
offsets specified in imm
.

Each 128-bit chunk is treated independently (i.e., the value for
the is i-th 128-bit chunk of dest
is calculated with the i-th
128-bit chunks of left
and right
).
