_mm256_hsubs_epi16

Horizontally subtracts adjacent signed packed 16-bit integer data elements of two vectors with saturation. The corresponding Intel® AVX2 instruction is VPHSUBSW.

Syntax

extern __m256i _mm256_hsubs_epi16(__m256i s1, __m256i s2);

Arguments

s1

integer source vector used for the operation

s2

integer source vector used for the operation

Description

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.

Returns

Result of the horizontal subtraction operation with saturation.
