Abstract
A processor may include a physical register file and a register renamer. The register renamer may be organized into even and odd banks of entries, where each entry stores an identifier of a physical register. The register renamer may be indexed by a register number of an architected register, such that the renamer maps a particular architected register to a corresponding physical register. Individual entries of the renamer may correspond to architected register aliases of a given size. Renaming aliases that are larger than the given size may involve accessing multiple entries of the renamer, while renaming aliases that are smaller than the given size may involve accessing a single renamer entry.
