          Appeal No. 96-2237                                                          
          Application 08/113,509                                                      



                                       OPINION                                        
                    We sustain the outstanding rejection of claim 20                  
          only and reverse the rejection of claims 14 through 19 and 21               
          through 26.                                                                 
                    Johnson operates his RISC processor system utilizing              
          a shared address bus in a manner to accommodate both pipelined              
          and burst modes of operation where, in the burst mode, simul-               
          taneous                                                                     


          or concurrent transfers of data and instructions over inde-                 
          pendent data and instruction busses occurs.  In pipelined                   
          instruction and data accesses, the pipelined or second in-                  
          struction access cannot complete until the first access has                 
          been completed.  Addition- ally, only instruction accesses may              
          be pipelined or only data accesses may be pipelined but not                 
          either in a sequential    order.  Note column 6, lines 8                    
          through 14, and column 7, lines 9 through 14.  Therefore, the               
          pipelined teachings of Johnson may not be used by the examiner              
          to reject independent claims 14 and 21 on appeal which require              
          that the first and second access cycles be either a data
