 Arm 64-bit (64 bits)/ NEON  View official documentation
 Location: Math Functions  >  Vector Approximate Reciprocal Square Root Estimate
 Supported Architectures: A32, A64
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:

float16x4_t

Example:
#include <arm_neon.h>
#include <stdio.h>
int main() {
 float16x4_t a = vdup_n_f16(1.0);
 float16x4_t result = vrsqrte_f16(a);
 float16_t output[4];
 vst1_f16(output, result);
 printf("Result: %f %f %f %f\n", output[0], output[1], output[2], output[3]);

 return 0;
}
