Intel 64-bit (64 bits)/ SSE4.2 View official documentation

Location: >
CPU Extensions: SSSE3

Purpose:

Compute the absolute value of packed signed 8-bit integers in a, and store the unsigned results in output.

Result:

A 64-bit vector of 8 x 8-bit signed integers that hold the absolute values of the input elements.

Example:

#include <tmmintrin.h>
#include <stdio.h>
int main() {
 __m64 a = _mm_set_pi8(-1, 2, -3, 4, -5, 6, -7, 8);
 __m64 d = _mm_abs_pi8(a);

 return 0;
}
