Neonpoly8x8_tvuzp1_p8(poly8x8_t a, poly8x8_t b)Vector manipulation / Unzip elements
Description
Unzip vectors (primary). This instruction reads corresponding even-numbered vector elements from the two source SIMD&FP registers, starting at zero, places the result from the first source register into consecutive elements in the lower half of a vector, and the result from the second source register into consecutive elements in the upper half of a vector, and writes the vector to the destination SIMD&FP register.
