128-bit SVE
Within each 128-bit segment, for each 8-bit index from (2), if 0 ≤ index < 16, set (3) to the 8-bit element at that index in the segment from (1), otherwise set (3) to zero.
256-bit SVE
Within each 128-bit segment, for each 8-bit index from (2), if 0 ≤ index < 16, set (3) to the 8-bit element at that index in the segment from (1), otherwise set (3) to zero.
512-bit SVE
Within each 128-bit segment, for each 8-bit index from (2), if 0 ≤ index < 16, set (3) to the 8-bit element at that index in the segment from (1), otherwise set (3) to zero.

1024-bit SVE
Within each 128-bit segment, for each 8-bit index from (2), if 0 ≤ index < 16, set (3) to the 8-bit element at that index in the segment from (1), otherwise set (3) to zero.
2048-bit SVE
Within each 128-bit segment, for each 8-bit index from (2), if 0 ≤ index < 16, set (3) to the 8-bit element at that index in the segment from (1), otherwise set (3) to zero.
