Abstract
A data processing apparatus, having a visible register map for associating physical registers with logical registers. Instructions involving register-to-register transfers are executed by altering the association between the physical registers and the logical registers, without actually transferring data between the registers, so as to avoid logically redundant operations and to take such instructions out of the critical path of execution.
