## 128-bit SVE

For each group of four unsigned 8-bit integers from (1) and signed 8-bit integers from (2), compute the dot-product, then add the result to the corresponding 32-bit integer accumulator from (3), setting (4) to the total.

## 256-bit SVE

For each group of four unsigned 8-bit integers from (1) and signed 8-bit integers from (2), compute the dot-product, then add the result to the corresponding 32-bit integer accumulator from (3), setting (4) to the total.

## 512-bit SVE

For each group of four unsigned 8-bit integers from (1) and signed 8-bit integers from (2), compute the dot-product, then add the result to the corresponding 32-bit integer accumulator from (3), setting (4) to the total.

## Larger sizes

## 1024-bit SVE

For each group of four unsigned 8-bit integers from (1) and signed 8-bit integers from (2), compute the dot-product, then add the result to the corresponding 32-bit integer accumulator from (3), setting (4) to the total.

## 2048-bit SVE

For each group of four unsigned 8-bit integers from (1) and signed 8-bit integers from (2), compute the dot-product, then add the result to the corresponding 32-bit integer accumulator from (3), setting (4) to the total.
