          Appeal No. 1996-3708                                                        
          Application 07/474,742                                                      


               We find that the Examiner has failed to show that each                 
          limitation of the claims is anticipated by the prior art.  In               
          particular the Examiner has not shown that Engels discloses a               
          communications bus or a central core which contains an                      
          interface with the communications bus, and an encoder.  We                  
          find that the Engels reference discloses a HOST which                       
          generates data and transmits it to boards which contain                     
          several DSPs.  Further we find that each DSP individually                   
          interfaces with the host.  We find that the Engels reference                
          fails to disclose a core which interfaces with a                            
          communications bus, decodes data received from the                          
          communications bus and transmits the data to the signal                     
          processor.  We find that Engels fails to disclose Appellants'               
          claimed core which provides all three functions of                          
          interfacing, decoding and transmitting.  Thus, we will not                  
          sustain the Examiner’s rejection of claims 18 and 19 under 35               
          U.S.C. § 102.                                                               
                            The 35 U.S.C. § 103 Rejection                             
               Next we consider the rejection of the claims under  35                 
          U.S.C. § 103 as being obvious over Engels in view of the                    


                                         11
