# UDOT (2-way, vectors): Unsigned integer dot product

UDOT Zda.S, Zn.H, Zm.H (SVE2.1 (SME2

## 128-bit SVE

For each pair of unsigned 16-bit integers from (1) and (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 pair of unsigned 16-bit integers from (1) and (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 pair of unsigned 16-bit integers from (1) and (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 pair of unsigned 16-bit integers from (1) and (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 pair of unsigned 16-bit integers from (1) and (2), compute the dot-product, then add the result to the corresponding 32-bit integer accumulator from (3), setting (4) to the total.
