128-bit SVE
For each odd signed 16-bit integer from (1) and even signed 16-bit integer from (2) set the double-width (4) to sat( (3) − sat( (1) * (2) << 1 ) ), with signed saturation to 0x7FFFFFFF or −0x80000000.
256-bit SVE
For each odd signed 16-bit integer from (1) and even signed 16-bit integer from (2) set the double-width (4) to sat( (3) − sat( (1) * (2) << 1 ) ), with signed saturation to 0x7FFFFFFF or −0x80000000.
512-bit SVE
For each odd signed 16-bit integer from (1) and even signed 16-bit integer from (2) set the double-width (4) to sat( (3) − sat( (1) * (2) << 1 ) ), with signed saturation to 0x7FFFFFFF or −0x80000000.
