Abstract:
A method and apparatus for allowing an out-of-order processor to reuse an in- use physical register is disclosed herein. The method and apparatus uses identifiers, such as tokens and / or other identifiers in a rename map table (RMT) and a physical register file (PRF), to indicate whether an instruction result is allowed or disallowed to be written into a physical register.
