ABSTRACT:
Methods and systems are disclosed for exploring instruction-level parallelism in superscalar processors by renaming stack entries. In a first embodiment, the stack renaming is implemented in a parallel structure that renames the instructions in parallel. In a second embodiment, the stack renaming is implemented in a serial structure that renames the instructions serially. In a third embodiment, the stack renaming is implemented in a combined parallel-serial structure that renames the instruction partially in parallel and partially in series.
