128-bit SVE

For each even signed 16-bit integer calculate (1) * (2), and subtract that from the 32-bit integer from (3), then set (4) to the result.

256-bit SVE

For each even signed 16-bit integer calculate (1) * (2), and subtract that from the 32-bit integer from (3), then set (4) to the result.

512-bit SVE

For each even signed 16-bit integer calculate (1) * (2), and subtract that from the 32-bit integer from (3), then set (4) to the result.
