Vector Approximate Reciprocal Square Root
Supported Architectures: v7, A32, A64
Supported Architectures: v7, 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:
uint32x2_t
Example:
#include <arm_neon.h>
#include <stdio.h>
int main() {
uint32x2_t a = {
4, 9
};
uint32x2_t result = vrsqrte_u32(a);
uint32_t out[2];
vst1_u32(out, result);
for (int i = 0; i < 2; i++) {
printf("%u ", out[i]);
}
printf("\n");
return 0;
}Prototypes
Assembly Instruction:
URSQRTE
Usage:
uint32x2_t result =
vrsqrte_u32(
uint32x2_t a
)
