Purpose:
Absolute value (vector). This instruction calculates the absolute value of each vector element in the source SIMD&FP register, puts the result into a vector, and writes the vector to the destination SIMD&FP register.
Result:
int8x8_t
Example:
#include <arm_neon.h>
#include <stdio.h>
int main() {
int8_t input_data[8] = {
-1, 2, -3, 4, -5, 6, -7, 8
};
int8x8_t a = vld1_s8(input_data);
int8x8_t d = vabs_s8(a);
int8_t result_data[8];
vst1_s8(result_data, d);
for (int i = 0; i < 8; i++) {
printf("%d ", result_data[i]);
}
printf("\n");
return 0;
