128-bit SVE
Multiply each odd signed 16-bit integer from (2), with the signed 16-bit integer specified by imm from (1), then add this to the 32-bit integer from (3), and set (4) to the result.
256-bit SVE
Multiply each odd signed 16-bit integer from (2), with the signed 16-bit integer specified by imm from (1), then add this to the 32-bit integer from (3), and set (4) to the result.
512-bit SVE
Multiply each odd signed 16-bit integer from (2), with the signed 16-bit integer specified by imm from (1), then add this to the 32-bit integer from (3), and set (4) to the result.
