Neonuint32x2_tvrsqrte_u32(uint32x2_t a)Vector arithmetic / Reciprocal / Reciprocal square-root estimate
Description
Unsigned Reciprocal Square Root Estimate. This instruction reads each vector element from the source SIMD&FP register, calculates an approximate inverse square root for each value, places the result into a vector, and writes the vector to the destination SIMD&FP register. All the values in this instruction are unsigned integer values.
