Intel® C++ Compiler 16.0 User and Reference Guide
Horizontally subtracts adjacent signed packed 16-bit integer data elements of two vectors with saturation. The corresponding Intel® AVX2 instruction is VPHSUBSW.
extern __m256i _mm256_hsubs_epi16(__m256i s1, __m256i s2); |
s1 |
integer source vector used for the operation |
s2 |
integer source vector used for the operation |
Performs horizontal subtraction on each adjacent pair of 16-bit signed integers by subtracting the most significant word from the least significant word of each pair in source vectors s1 and s2. The signed, saturated 16-bit results are packed to the destination vector.
Result of the horizontal subtraction operation with saturation.
