Pack signed word/doubleword integers to unsigned byte/word integers and saturates. The corresponding Intel® AVX 2 instructions are VPACKUSWB and VPACKUSDW
extern __m256i _mm256_packus_epi16(__m256i a, __m256i b); |
extern __m256i _mm256_packus_epi32(__m256i a, __m256i b); |
a |
integer source operand used for the operation |
b |
integer source operand used for the operation |
The _mm256_packus_epi16 intrinsic converts 16 packed unsigned word integers from the first and the second source operands into 32 packed usigned byte integers. The _mm256_packus_epi32 intrinsic converts 8 packed unsigned doubleword integers from the first and the second source operands into 16 unpacked signed word integers.
Result of the pack operation.
