Purpose:
Add packed 16-bit integers in a and b, and store the results in output.
Result:
A 128-bit vector containing the result of the addition.
Example:
#include <emmintrin.h>
#include <stdio.h>
int main() {
__m128i a = _mm_set_epi16(1, 2, 3, 4, 5, 6, 7, 8);
__m128i b = _mm_set_epi16(8, 7, 6, 5, 4, 3, 2, 1);
__m128i result = _mm_add_epi16(a, b);
int16_t res[8];
_mm_storeu_si128((__m128i*)res, result);
for (int i = 0; i < 8; ++i) {
printf("%d ", res[i]);
}
printf("\n");
return 0;
