Abstract
An apparatus and method for renaming a plurality of storage register files implemented. A rename register in a unified rename buffer provides temporary storage for instruction operands resulting from the execution of the instruction to the operands being written to an architected register in one of storage register files. A rename map associates the rename register with the corresponding storage register, which may be in any of the storage register files. The rename registers may simultaneously store data values of different types. Rename map entries include a tag which operates to identify the register file containing the storage register.
