_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.

Intel's compilers may or may not optimize to the same degree for non-Intel microprocessors for optimizations that are not unique to Intel microprocessors. These optimizations include SSE2, SSE3, and SSSE3 instruction sets and other optimizations. Intel does not guarantee the availability, functionality, or effectiveness of any optimization on microprocessors not manufactured by Intel. Microprocessor-dependent optimizations in this product are intended for use with Intel microprocessors. Certain optimizations not specific to Intel microarchitecture are reserved for Intel microprocessors.
