          Appeal No. 96-2499                                                          
          Application No. 08/204,521                                                  


                    (a) a memory array for providing a plurality of                   
          addressable entries for renaming said flag registers;                       
                    (b) array read logic coupled to said memory array                 
          and coupled to said logic for supplying, said instruction                   
          decode and fetch unit for addressing said memory array by said              
          flag registers and for supplying pointers to a set of physical              
          registers assigned to said flag registers;                                  
                    (c) dependency logic for determining if said given                
          instruction of said current set of instructions reads a flag                
          register that is output by said previous instruction of said                
          current set of instructions; and                                            
                    (d) comparison logic responsive to said dependency                
          logic for determining if flags of said flag register read by                
          said given instruction are a superset of flags of said flag                 
          register output by said previous instruction of said current                
          set of instructions.                                                        


               The examiner relies on the following reference:                        
          Cocke et al. (Cocke)          4,992,938                Feb. 12,             
          1991                                                                        


               Claims 1 through 3, 5 through 40 and 42 through 50 stand               
          rejected under 35 U.S.C. § 103 as unpatentable over Cocke.                  
               Reference is made to the brief and answer for the                      
          respective positions of appellants and the examiner.
