View official documentation
Purpose:
This instruction adds corresponding unsigned 8-bit integer elements of two vectors.
Result:
float64x2_t
Example:
#include <arm_neon.h>
#include <stdio.h>
int main() {
float64x2_t a = {
1.5, 2.5
};
float64x2_t b = {
3.0, 4.0
};
float64x2_t result = vaddq_f64(a, b);
double* res = (double*)&result;
for (int i = 0; i < 2; ++i) {
printf("%f ", res[i]);
}
printf("\n");
return 0;
}Prototypes
Assembly Instruction:
FADD
Usage:
float64x2_t result =
vaddq_f64(
float64x2_t a, float64x2_t b
)
