          Appeal No. 95-4708                                                          
          Application 08/127,782                                                      

          at the end of the clock cycle is as if all operations targeting             
          the same area were performed.  That is the proper interpretation.           
          Neither the appellants nor the examiner urges a different view.             
               The issues on appeal center about whether Hinton and Johnson           
          discloses or suggests, whether alone or in combination with each            
          other, the writing of results into the same targeted register               
          part or portion within the same clock cycle, a feature which the            
          examiner has not denied is required by all the independent                  
          claims.  The appellants argue that they do not.  We agree.                  
               With regard to the register file RF 6 of Hinton, the                   
          examiner stated (answer at 3):                                              
               The register file (RF) 6 is multi-ported, including two                
               write ports.  The RF can receive the results of two                    
               operations simultaneously.  The REG coprocessors 10 can                
               write the results of an arithmetic operation to the RF                 
               6, simultaneously with the MEM coprocessors 10 loading                 
               an operand to the RF 6 from external memory.  In other                 
               words, results of concurrently executing micro-                        
               operations can be written to the RF 6 simultaneously.                  
          Also, in response to the appellants’ argument, the examiner                 
          pointed to a portion of Hinton which defines two access ports for           
          the register file 6 which (column 12, lines 64-66) "allow LOAD              
          data from a previous read operation and STORE data from a current           
          write access to be processed in the register simultaneously."               
               The problem with the examiner’s position is that Hinton                
          evidently is discussing simultaneous access to the register file            

                                          4
