## 128-bit SVE

Shift each signed 16-bit integer from (2) by the corresponding signed 16-bit integer from (1), with signed saturation to 0x7FFF or −0x8000 on overflow, setting (3) to the result. If (1) ≥ 0, this shifts left by (1), otherwise it shifts right by −(1).

## 256-bit SVE

Shift each signed 16-bit integer from (2) by the corresponding signed 16-bit integer from (1), with signed saturation to 0x7FFF or −0x8000 on overflow, setting (3) to the result. If (1) ≥ 0, this shifts left by (1), otherwise it shifts right by −(1).

## 512-bit SVE

Shift each signed 16-bit integer from (2) by the corresponding signed 16-bit integer from (1), with signed saturation to 0x7FFF or −0x8000 on overflow, setting (3) to the result. If (1) ≥ 0, this shifts left by (1), otherwise it shifts right by −(1).

## Larger sizes

## 1024-bit SVE

Shift each signed 16-bit integer from (2) by the corresponding signed 16-bit integer from (1), with signed saturation to 0x7FFF or −0x8000 on overflow, setting (3) to the result. If (1) ≥ 0, this shifts left by (1), otherwise it shifts right by −(1).

## 2048-bit SVE

Shift each signed 16-bit integer from (2) by the corresponding signed 16-bit integer from (1), with signed saturation to 0x7FFF or −0x8000 on overflow, setting (3) to the result. If (1) ≥ 0, this shifts left by (1), otherwise it shifts right by −(1).
