128-bit SVE
For each odd signed 16-bit integer calculate (1) * (2), and add that to the 32-bit integer from (3), then set (4) to the result.
256-bit SVE
For each odd signed 16-bit integer calculate (1) * (2), and add that to the 32-bit integer from (3), then set (4) to the result.
512-bit SVE
For each odd signed 16-bit integer calculate (1) * (2), and add that to the 32-bit integer from (3), then set (4) to the result.
