128-bit SVE

For each 32-bit integer set the even 16-bit elements of (2) to (1) >> const, and zero odd elements. The shift amount is limited to 1 ≤ const ≤ 16.
256-bit SVE

For each 32-bit integer set the even 16-bit elements of (2) to (1) >> const, and zero odd elements. The shift amount is limited to 1 ≤ const ≤ 16.
512-bit SVE

For each 32-bit integer set the even 16-bit elements of (2) to (1) >> const, and zero odd elements. The shift amount is limited to 1 ≤ const ≤ 16.
