An apparatus and system may include a logical index register to be mapped onto a selected one of a plurality of physical registers, and a logical data register to be mapped onto the same selected physical register. An article, including a machine-accessible medium, may contain data capable of causing a machine to carry out a register mapping method, including mapping at least one logical index register onto a selected one of a plurality of physical registers, and mapping at least one logical data register onto the same selected physical register.
