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:
float32x4_t
Example:
#include <arm_neon.h>
#include <stdio.h>
int main() {
float32_t data[4] = {
-1.0f, 2.0f, -3.0f, 4.0f
};
float32x4_t a = vld1q_f32(data);
float32x4_t result = vabsq_f32(a);
float32_t result_data[4];
vst1q_f32(result_data, result);
for (int i = 0; i < 4; ++i) {
printf("%f ", result_data[i]);
}
printf("\n");
return 0;
}Prototypes
Assembly Instruction:
FABS
Usage:
float32x4_t result =
vabsq_f32(
float32x4_t a
)
