   * physical register base OOO must have Dual-RAT architecture or equivalent
structure.FRAT:FrontRAT, RRAT:RetireRAT;
   * i,f prefix mean int and fp
   * RAT for all Renaming logic, random accessible checkpointing is used, but
only update when instruction retires.
   * FRAT will be read twice and written once per instruction;
   * RRAT will be write once per instruction when committing and reads out all
when context switch
   *
   * RAM scheme has # ARchi Reg entry with each entry hold phy reg tag,
   * CAM scheme has # Phy Reg entry with each entry hold ARchi reg tag,
   *
   * RAM-based RAT is duplicated/partitioned for each different hardware threads
   * CAM-based RAT is shared for all hardware threads
   * With SMT, RAT is partitioned and tagged. RAM-based RAT needs to have N
(N-way SMT) sets of entries, with each set for a thread.
   * The RAT control logic will determine different sets to use for different
threads. But it does not need extra tag bits in the entries.
   * However, CAM-based RAT need extra tag bits to distinguish the architecture
register ids for different threads.

   *
   * checkpointing of RAT and RRAT are both for architecture state recovery with
events including mis-speculation;
   * Checkpointing is easier to implement in CAM than in RAM based RAT, despite
of the inferior scalabilty of the CAM-based RATs.
   * McPAT assumes at least 1 checkpoint for CAM-based RATs, and no more than 4
checkpoints (based on MIPS designs) for RAM based RATs,
   * thus CAM-based RAT does not need RRAT
   * Although no Dual-RAT is needed in RS-based OOO processors, since archi
RegFile contains the committed register values,
   * a RRAT or GC (not both) will speedup the mis-speculation recovery. Thus,
when RAM-RAT does not have any GC, McPAT assumes the existence of a RRAT.
   *
   * RAM-base RAT does not need to scan/search all contents during instruction
commit, since the ROB for RAM-based RAT contains the ARF-PRF mapping that is
used for index the RAT entry to be updated.
   *
   * Both RAM and CAM have same DCL
