Vector Add
Purpose:
Add packed 8-bit integers in a and b, and store the results in dst.
Result:
A 128-bit vector containing the result of the addition.
Example:
#include <emmintrin.h>
#include <stdio.h>
int main() {
__m128i a = _mm_setr_epi8(1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16);
__m128i b = _mm_setr_epi8(16, 15, 14, 13, 12, 11, 10, 9, 8, 7, 6, 5, 4, 3, 2, 1);
__m128i result = _mm_add_epi8(a, b);
int8_t res[16];
_mm_storeu_si128((__m128i*)res, result);
for (int i = 0; i < 16; i++) {
printf("%d ", res[i]);
}
printf("\n");
return 0;
