          Appeal No. 1997-0300                                                        
          Application 08/138,790                                                      

                    We find that Ardini teaches a microprocessor system               
          where data to be written to memory is sent from the processor               
          to a write buffer (buffer) for temporary storage in the                     
          buffer.  See column 5, lines 45 through 54.  Ardini teaches                 
          that the micro- processor writes data as either 16 or 32 bits               
          and that both    the write buffer and memory can accept 64                  
          bits of data.  See column 4, lines 1 through 5 and 22 through               
          25.  We find that Ardini teaches making a determination of                  
          whether the data written to the buffer is to be stored in                   
          successive memory locations.  If                                            
          so, the data is merged together and stored in memory with one               
          write from the write buffer (i.e. data from the                             
          microprocessor, which contains fewer bytes than the width of                
          the memory are merged with other data into one write to one                 
          memory location).  See column 1, lines 51 through 66, and                   
          column 5, lines 13  through 44.  We find that Ardini teaches                
          that the timesaving advantage of the buffer is that it reduces              
          the number of writes
