128-bit SVE

For each odd unsigned 8-bit integer calculate (1) * (2), and add that to the 16-bit integer from (3), then set (4) to the result.

256-bit SVE

For each odd unsigned 8-bit integer calculate (1) * (2), and add that to the 16-bit integer from (3), then set (4) to the result.

512-bit SVE

For each odd unsigned 8-bit integer calculate (1) * (2), and add that to the 16-bit integer from (3), then set (4) to the result.
