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

128-bit SVE

For each pair of unsigned 8-bit integers from (1) and (2), compute the dot-product (A*B+C*D), then add the result to the corresponding 16-bit integer accumulator from (3), setting (4) to the total.

256-bit SVE

For each pair of unsigned 8-bit integers from (1) and (2), compute the dot-product (A*B+C*D), then add the result to the corresponding 16-bit integer accumulator from (3), setting (4) to the total.

512-bit SVE

For each pair of unsigned 8-bit integers from (1) and (2), compute the dot-product (A*B+C*D), then add the result to the corresponding 16-bit integer accumulator from (3), setting (4) to the total.
