_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.
