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 source vectors
s1
