如何在AVX2中将32位无符号整数转换为16位无符号整数？

#include <immintrin.h>

void convertUInt32toUInt16(const uint32_t* src, uint16_t* dest, size_t count) {
    size_t i = 0;
    for (; i + 8 <= count; i += 8) {
        __m256i data = _mm256_loadu_si256((const __m256i*)(src + i));
        __m256i result = _mm256_cvtepu32_epi16(data);
        _mm256_storeu_si256((__m256i*)(dest + i), result);
    }

    for (; i < count; ++i) {
        dest[i] = static_cast<uint16_t>(src[i]);
    }
}
