128-bit SVE
For each even signed 16-bit integer set the double-width (4) to sat( (3) + sat( (1) * (2) << 1 ) ), with signed saturation to 0x7FFFFFFF or −0x80000000. Within each 128-bit segment, the value used from (1) is specified by imm.
256-bit SVE
For each even signed 16-bit integer set the double-width (4) to sat( (3) + sat( (1) * (2) << 1 ) ), with signed saturation to 0x7FFFFFFF or −0x80000000. Within each 128-bit segment, the value used from (1) is specified by imm.
512-bit SVE
For each even signed 16-bit integer set the double-width (4) to sat( (3) + sat( (1) * (2) << 1 ) ), with signed saturation to 0x7FFFFFFF or −0x80000000. Within each 128-bit segment, the value used from (1) is specified by imm.
