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:
float16x8_t
Example:
#include <arm_neon.h>
#include <stdio.h>
int main() {
float16_t a_data[8] = {
-1.5f, 2.0f, -3.0f, 4.0f, -5.0f, 6.0f, -7.0f, 8.0f
};
float16x8_t a = vld1q_f16(a_data);
float16x8_t result = vabsq_f16(a);
float16_t result_data[8];
vst1q_f16(result_data, result);
printf("Absolute values:\n");
for (int i = 0; i < 8; i++) {
printf("%f ", result_data[i]);
}
printf("\n");
return 0;
