          Appeal No. 1998-2661                                                        
          Application 08/633,267                                                      

          to the instructions as they enter this VAIW as expressed in                 
          the discussion between columns 3 through 5 of Deosaran and                  
          most succintly expressed at the bottom of column 3 at lines 59              
          through 62 "[e]ach instruction's tag remains constant as long               
          as the instruction remains in the window.  This tag is also                 
          associated with the location in a temp buffer (discussed                    
          below) that the corresponding instruction's output will be                  
          stored."                                                                    
               From an artisan's perspective, this temporary buffer is                
          clearly analogous to the claimed physical rename registers in               
          a manner well-expressed earlier in this opinion in terms of                 
          their functionality.  Thus, it is apparent that this temporary              
          buffer is reassigned according to the tagging scheme and                    
          associated with an instruction before the availability of the               
          buffer to receive the result of that instruction in accordance              
          with that which is set forth in claim 1 on appeal.  This pre-               
          assignment is necessary and indirectly expressed again at                   
          column 5, lines 29 through 32 indicating "the processor                     
          implementing the present invention uses the tag of an                       
          instruction as the temp buffer address of that instruction's                
          result."  Therefore, we only sustain the rejection of claim 1               

                                         17
