128-bit SVE
For each pair of 8-bit integers, considered as the real and imaginary components of a complex number, set (3) to (2) + ( (1) rotated by 90° ), with signed saturation of each component to 0x7F or −0x80 on overflow.
256-bit SVE
For each pair of 8-bit integers, considered as the real and imaginary components of a complex number, set (3) to (2) + ( (1) rotated by 90° ), with signed saturation of each component to 0x7F or −0x80 on overflow.
512-bit SVE
