## 128-bit SVE

Multiply each even signed 32-bit integer from (2), with the signed 32-bit integer specified by `imm`

from (1), then subtract this from the 64-bit integer from (3), and set (4) to the result.

## 256-bit SVE

Multiply each even signed 32-bit integer from (2), with the signed 32-bit integer specified by `imm`

from (1), then subtract this from the 64-bit integer from (3), and set (4) to the result.

## 512-bit SVE

Multiply each even signed 32-bit integer from (2), with the signed 32-bit integer specified by `imm`

from (1), then subtract this from the 64-bit integer from (3), and set (4) to the result.

## Larger sizes

## 1024-bit SVE

Multiply each even signed 32-bit integer from (2), with the signed 32-bit integer specified by `imm`

from (1), then subtract this from the 64-bit integer from (3), and set (4) to the result.

## 2048-bit SVE

Multiply each even signed 32-bit integer from (2), with the signed 32-bit integer specified by `imm`

from (1), then subtract this from the 64-bit integer from (3), and set (4) to the result.
