_mm256_mulhi

Multiplies signed packed 16/32-bit integer data elements of two vectors and stores high bits. The corresponding Intel® AVX2 instruction is VPMULHW.

Syntax

extern __m256i _mm256_mulhi_epi16(__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 signed multiply of the packed signed 16-bit integers in the first and second source vectors, s1 and s2, and stores the high 16 bits of each intermediate 32-bit result in the destination vector.

Returns

Result of the multiplication operation.
