128-bit SVE
Add and subtract adjacent pairs of 16-bit elements. Set each even element of (3) to the sum of the corresponding pair from (1), and each odd element to the difference (lower minus upper) of the corresponding pair from (2).
256-bit SVE
Add and subtract adjacent pairs of 16-bit elements. Set each even element of (3) to the sum of the corresponding pair from (1), and each odd element to the difference (lower minus upper) of the corresponding pair from (2).
512-bit SVE
Add and subtract adjacent pairs of 16-bit elements. Set each even element of (3) to the sum of the corresponding pair from (1), and each odd element to the difference (lower minus upper) of the corresponding pair from (2).

1024-bit SVE
Add and subtract adjacent pairs of 16-bit elements. Set each even element of (3) to the sum of the corresponding pair from (1), and each odd element to the difference (lower minus upper) of the corresponding pair from (2).
2048-bit SVE
Add and subtract adjacent pairs of 16-bit elements. Set each even element of (3) to the sum of the corresponding pair from (1), and each odd element to the difference (lower minus upper) of the corresponding pair from (2).
