128-bit SVE
For each even unsigned 32-bit integer calculate abs( (1) − (2) ), and add that to the 64-bit integer from (3), then set (4) to the result.
256-bit SVE
For each even unsigned 32-bit integer calculate abs( (1) − (2) ), and add that to the 64-bit integer from (3), then set (4) to the result.
512-bit SVE
For each even unsigned 32-bit integer calculate abs( (1) − (2) ), and add that to the 64-bit integer from (3), then set (4) to the result.
