## 128-bit SVE

For each pair of 16-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 0x7FFF or −0x8000 on overflow.

## 256-bit SVE

For each pair of 16-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 0x7FFF or −0x8000 on overflow.

## 512-bit SVE

For each pair of 16-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 0x7FFF or −0x8000 on overflow.
