_mm256_packus_epi16/32

Pack signed word/doubleword integers to unsigned byte/word integers and saturates. The corresponding Intel® AVX2 instruction is VPACKUSWB or VPACKUSDW.

Syntax

extern __m256i _mm256_packus_epi16(__m256i a, __m256i b);

extern __m256i _mm256_packus_epi32(__m256i a, __m256i b);

Arguments

`a`	integer source operand used for the operation
`b`	integer source operand used for the operation

Description

The _mm256_packus_epi16 intrinsic converts 16 packed unsigned word integers from source operands a and b into 32 packed unsigned byte integers. The _mm256_packus_epi32 intrinsic converts eight packed unsigned doubleword integers from the source operands a and b into 16 unpacked signed word integers.

Returns

Result of the pack operation.
