_mm256_mullo_epi16/32

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

Syntax

extern __m256i _mm256_mullo_epi16(__m256i s1, __m256i s2);

extern __m256i _mm256_mullo_epi32(__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- or 32-bit integers in the first and second source vectors, s1 and s2, and stores the low 16- or 32-bits of each intermediate 32- or 64-bit result in the destination vector.

Returns

Result of the multiplication operation.
