Neonuint8x16_tvzip1q_u8(uint8x16_t a, uint8x16_t b)Vector manipulation / Zip elements
Description
Zip vectors (primary). This instruction reads adjacent vector elements from the lower half of two source SIMD&FP registers as pairs, interleaves the pairs and places them into a vector, and writes the vector to the destination SIMD&FP register. The first pair from the first source register is placed into the two lowest vector elements, with subsequent pairs taken alternately from each source register.
