_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.

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.
