128-bit SVE

For each even unsigned 16-bit integer calculate abs( (1) − (2) ), and add that to the 32-bit integer from (3), then set (4) to the result.

256-bit SVE

For each even unsigned 16-bit integer calculate abs( (1) − (2) ), and add that to the 32-bit integer from (3), then set (4) to the result.

512-bit SVE

For each even unsigned 16-bit integer calculate abs( (1) − (2) ), and add that to the 32-bit integer from (3), then set (4) to the result.
