Neonint16x8_tvuqaddq_s16(int16x8_t a, uint16x8_t b)Vector arithmetic / Add / Saturating addition
Description
Signed saturating Accumulate of Unsigned value. This instruction adds the unsigned integer values of the vector elements in the source SIMD&FP register to corresponding signed integer values of the vector elements in the destination SIMD&FP register, and writes the resulting signed integer values to the destination SIMD&FP register.
