_mm256_max_epu8/16/32

Determines the maximum value between two vectors with packed unsigned byte/word/doubleword integers. The corresponding Intel® AVX2 instruction is VPMAXUB, VPMAXUW, or VPMAXUD.

Syntax

extern __m256i _mm256_max_epu8(__m256i s1, __m256i s2);

extern __m256i _mm256_max_epu16(__m256i s1, __m256i s2);

extern __m256i _mm256_max_epu32(__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 unsigned byte, word, or doubleword integers in the second source vector, s2 and the first source vector, s1, and returns the maximum value for each pair of integers to the destination vector.

Returns

Destination vector with result of the compare operation.
