Vector Add
Purpose:
Add packed 16-bit integers in a and b, and store the results in output.
Result:
A 256-bit vector that contains the result of the addition.
Example:
#include <immintrin.h>
#include <stdio.h>
int main() {
__m256i a = _mm256_set_epi16(1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16);
__m256i b = _mm256_set_epi16(16, 15, 14, 13, 12, 11, 10, 9, 8, 7, 6, 5, 4, 3, 2, 1);
__m256i result = _mm256_add_epi16(a, b);
int16_t res[16];
_mm256_storeu_si256((__m256i*)res, result);
for (int i = 0; i < 16; ++i) {
printf("%d ", res[i]);
}
printf("\n");
return 0;
