"This requires space in an instruction for quite a large address. It is often available on CISC machines which have variable-length instructions, such as x86. Some RISC machines have a special Load Upper Literal instruction which places a 16- or 20-bit constant in the top half of a register. That can then be used as the base register in a base-plus-offset addressing mode which supplies the low-order 16 or 12 bits. The combination allows a ful… " - Branch addressing mode
