128-bit SVE
For each signed 16-bit integer, set (4) as shown, given f(x,y) = ((x << 15) + y + 0x4000) >> 15, with signed saturation to 0x7FFF or −0x8000. Within each 128-bit segment, the pair of values used from (1) is specified by imm.
256-bit SVE
For each signed 16-bit integer, set (4) as shown, given f(x,y) = ((x << 15) + y + 0x4000) >> 15, with signed saturation to 0x7FFF or −0x8000. Within each 128-bit segment, the pair of values used from (1) is specified by imm.
512-bit SVE
For each signed 16-bit integer, set (4) as shown, given f(x,y) = ((x << 15) + y + 0x4000) >> 15, with signed saturation to 0x7FFF or −0x8000. Within each 128-bit segment, the pair of values used from (1) is specified by imm.
