Syntax

extern __m256i _mm256_cvtepu16_epi32(__m128i s1);
extern __m256i _mm256_cvtepu16_epi64(__m128i s1);
Arguments
s1
128-bit integer source vector used for the operation
Description
Performs a packed move with zero-extend operation to convert 16-bit [word] integers in the low bytes of the source vector,
s1
, to 32-bit [doubleword] or 64-bit [quadword] integers and stored as packed signed doubleword/quadword integers in the destination vector.
Returns
Result of the zero-extend operation.
