Determines the maximum value between two vectors with packed signed byte/word/doubleword integers. The corresponding Intel® AVX2 instruction is
VPMAXSB
,
VPMAXSW
, or
VPMAXSD
.

Syntax

extern __m256i _mm256_max_epi8(__m256i s1, __m256i s2);
extern __m256i _mm256_max_epi16(__m256i s1, __m256i s2);
extern __m256i _mm256_max_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 compare of the packed signed byte, word, or doubleword integers in source vectors
s1
and
s2
and returns the maximum value for each pair of integers to the destination vector.
Returns
Destination vector with result of the compare operation.
