Abstract
In one aspect the present invention provides for an apparatus that includes at least two physical registers and a rename unit to assign at least one of the physical registers to an original register. The original register appears as a destination address in a micro-op. The apparatus includes a rename table having a location for recording the assigned physical register to the original register. The location has at least one bit for indicating whether the assigned physical register belongs to a first or a second class. The rename table is connected to the rename unit and is adapted to lookups of the assigned physical register.
