Neonuint8x8_tvqmovn_u16(uint16x8_t a)Move / Saturating narrow
Description
Unsigned saturating extract Narrow. This instruction reads each vector element from the source SIMD&FP register, saturates each value to half the original width, 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.
