## 128-bit SVE

For each odd unsigned 32-bit integer calculate (1) * (2), and add that to the 64-bit integer from (3), then set (4) to the result.

## 256-bit SVE

For each odd unsigned 32-bit integer calculate (1) * (2), and add that to the 64-bit integer from (3), then set (4) to the result.

## 512-bit SVE

For each odd unsigned 32-bit integer calculate (1) * (2), and add that to the 64-bit integer from (3), then set (4) to the result.

## Larger sizes

## 1024-bit SVE

For each odd unsigned 32-bit integer calculate (1) * (2), and add that to the 64-bit integer from (3), then set (4) to the result.

## 2048-bit SVE

For each odd unsigned 32-bit integer calculate (1) * (2), and add that to the 64-bit integer from (3), then set (4) to the result.
