_mm256_adds_epu8/16

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

Syntax

extern __m256i _mm256_adds_epu8(__m256i s1, __m256i s2);
extern __m256i _mm256_adds_epu16(__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, unsigned, 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 unsigned byte/word integer (that is, greater than
FFH/FFFFH
), the saturated value of
FFH/FFFFH
, respectively, is written to the destination vector.
Returns
Result of the addition operation.
