v128 Vector
Compute the sum of absolute differences (SADs) of quadruplets of unsigned 8-bit integers in "a" compared to those in "b", and store the 16-bit results in "dst".
Eight SADs are performed 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".
