View official documentation
Purpose:
Compute the absolute value of packed signed 16-bit integers in "a", and store the unsigned results in "dst".
Result:
__m512i
Example:
#include <immintrin.h>
#include <stdio.h>
int main() {
__m512i a = _mm512_set_epi16(-1, -200, 300, -400, 500, -600, 700, -800, 900, -1000, 1100, -1200, 1300, -1400, 1500, -1600, -1700, 1800, -1900, 2000, -2100, 2200, -2300, 2400, -2500, 2600, -2700, 2800, -2900, 3000, -3100, 3200);
__m512i r = _mm512_abs_epi16(a);
short* p = (short*)&r;
for (int i = 0; i < 32; i++)
printf("%d ", p[i]);
printf("\n");
return 0;
