# _mm256_hadds_epi16

Horizontally adds adjacent signed packed 16-bit integer data elements of two vectors with saturation. The corresponding Intel® AVX2 instruction is VPHADDSW.

## Syntax

extern __m256i _mm256_hadds_epi16(__m256i s1, __m256i s2);

## Arguments

s1 | integer source vector used for the operation
s2 | integer source vector used for the operation

## Description

Adds two adjacent, signed 16-bit integers horizontally from the source vectors s1 and s2, saturates the signed results, and packs the signed, saturated 16-bit results to the destination vector.

## Returns

Result of the horizontal addition operation with saturation.
