UABAL Zda.H, Zn.B, Zm.B (SVE2.3 (SME2.3

128-bit SVE

For each unsigned 8-bit integer calculate abs( (1) − (2) ), and add both results to the corresponding 16-bit integer accumulator from (3), setting (4) to the total.

256-bit SVE

For each unsigned 8-bit integer calculate abs( (1) − (2) ), and add both results to the corresponding 16-bit integer accumulator from (3), setting (4) to the total.

512-bit SVE

For each unsigned 8-bit integer calculate abs( (1) − (2) ), and add both results to the corresponding 16-bit integer accumulator from (3), setting (4) to the total.
