ABSTRACT:
In one embodiment, a renamer comprises a plurality of storage locations and compare circuitry. Each storage location is assigned to a respective renameable resource and is configured to store an identifier corresponding to a youngest instruction operation that writes the respective renameable resource. Coupled to receive an input representing one or more retiring instruction identifiers corresponding to instruction operations that are being retired, the compare circuitry is configured to detect a match between at least a first identifier in a first storage location and one of the retiring identifiers. An encoded form of the identifiers is logically divided into a plurality of fields, and the input comprises a first plurality of bit vectors. Each of the first plurality of bit vectors corresponds to a respective field and includes a bit position for each possible value of the respective field.
