# _mm256_adds_epi8/16

Adds the signed 8/16-bit integer data elements with saturation of two vectors. The corresponding Intel® AVX2 instruction is VPADDSB or VPADDSW.

## Syntax

extern __m256i _mm256_adds_epi8(__m256i s1, __m256i s2);

extern __m256i _mm256_adds_epi16(__m256i s1, __m256i s2);

## Arguments

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

## Description

Performs a SIMD add of the packed, signed, 8- or 16-bit integer data elements with saturation from the first source vector, s1, and corresponding elements of the second source vector, s2, and stores the packed integer results in the destination vector. When an individual byte/word result is beyond the range of a signed byte/word integer (that is, greater than 7FH/7FFFH or less than 80H/8000H), the saturated value of 7FH/7FFFH or 80H/8000H, respectively, is written to the destination vector.

## Returns

Result of the addition operation.
