          Appeal No. 2000-1356                                                        
          Application 07/979,772                                                      


          obviousness rejection of claim 45 over Lee.                                 
               Regarding claim 46, Appellants offer a mere conclusory                 
          statement.  Anyway, we find that the branch instruction in Lee              
          could obviously involve the resolution of a conflict regarding              
          the use of the same shifter while different kinds of branch                 
          instructions are being processed.  Therefore, we sustain the                
          obviousness rejection of claim 46 over Lee.                                 
               Regarding claim 47, Appellants offer no specific analysis              
          other than a mere conclusory statement.  At any rate, we find               
          that when a decision is made such as the one shown by step H2               
          in fig. 6 of Lee, an artisan would have employed a single bit               
          as a flag to denote the result of the decision.  Consequently,              
          we sustain the obviousness rejection of claim 47 over Lee.                  


               With respect to dependent claim 181, an artisan would                  
          have found it obvious to introduce additional arithmetic logic              
          units to Lee’s processor to facilitate the processing of                    
          instructions.  Therefore, we sustain the obviousness rejection              
          of claim 181 over Lee.                                                      
               Claim 48                                                               
               Appellants argue [brief, page 18] that “[a]s shown above,              
                                         -8-
