svuint16_t svabalt[_u16](svuint16_t op1, svuint8_t op2, svuint8_t op3)

## 128-bit SVE

For each odd unsigned 8-bit integer calculate abs( (1) − (2) ), and add that to the 16-bit integer from (3), then set (4) to the result.

## 256-bit SVE

For each odd unsigned 8-bit integer calculate abs( (1) − (2) ), and add that to the 16-bit integer from (3), then set (4) to the result.

## 512-bit SVE

For each odd unsigned 8-bit integer calculate abs( (1) − (2) ), and add that to the 16-bit integer from (3), then set (4) to the result.

## Larger sizes

## 1024-bit SVE

For each odd unsigned 8-bit integer calculate abs( (1) − (2) ), and add that to the 16-bit integer from (3), then set (4) to the result.

## 2048-bit SVE

For each odd unsigned 8-bit integer calculate abs( (1) − (2) ), and add that to the 16-bit integer from (3), then set (4) to the result.
