Purpose:
Floating-point Reciprocal Square Root Estimate. This instruction calculates an approximate square root for each vector element in the source SIMD&FP register, places the result in a vector, and writes the vector to the destination SIMD&FP register.
Result:
float64x1_t
Example:
#include <arm_neon.h>
#include <stdio.h>
int main() {
float64x1_t a = {
4.0
};
float64x1_t result = vrsqrte_f64(a);
double out[1];
vst1_f64(out, result);
for (int i = 0; i < 1; i++) {
printf("%f ", out[i]);
}
printf("\n");
return 0;
}Prototypes
Assembly Instruction:
FRSQRTE
Usage:
float64x1_t result =
vrsqrte_f64(
float64x1_t a
)
