128-bit SVE
For each pair of unsigned 16-bit integers from (1) and (2), compute the dot-product, then add the result to the corresponding 32-bit integer accumulator from (3), setting (4) to the total. Within each 128-bit segment, the pair of values used from (1) is specified by imm.
256-bit SVE
For each pair of unsigned 16-bit integers from (1) and (2), compute the dot-product, then add the result to the corresponding 32-bit integer accumulator from (3), setting (4) to the total. Within each 128-bit segment, the pair of values used from (1) is specified by imm.
512-bit SVE
For each pair of unsigned 16-bit integers from (1) and (2), compute the dot-product, then add the result to the corresponding 32-bit integer accumulator from (3), setting (4) to the total. Within each 128-bit segment, the pair of values used from (1) is specified by imm.
