EORTB
Interleaving exclusive OR (top, bottom)
Interleaving exclusive OR between the odd-numbered elements of the first source vector register and the even-numbered elements of the second source vector register, placing the result in the odd-numbered elements of the destination vector, leaving the even-numbered elements unchanged. This instruction is unpredicated.
