          Appeal No. 96-1741                                                          
          Application 08/160,111                                                      

          analysis as to why the presence of registers, as broadly                    
          recited in claim 7, would have been obvious to the artisan in               
          view of the applied prior art.  Appellants argue that Chu does              
          not show such a register at the output of the barrel rotator,               
          but this argument fails to address the obviousness of broadly               
          providing such a register.  Appellants also argue that “claims              
          7 and 46 require storage of both the output of the arithmetic               
          logic unit and the output of the barrel rotator during the                  
          same operation.  Neither Chu et al nor Vassiliadis et al show               
          the claimed simultaneous storage of these two outputs in any                
          mode” [brief, page 8].  We agree with the examiner that this                
          argument of appellants is not commensurate in scope with the                
          claimed invention.  We find nothing in claim 7 which requires               
          the simultaneous storage as argued by appellants.  Since                    
          appellants’ arguments are not persuasive of error by the                    
          examiner, we sustain the rejection of claims 7 and 46.                      
          With respect to claims 8 and 47 which are grouped                           
          together, the examiner asserts that Chu teaches a one’s                     
          constant source to supply a barrel rotator [answer, page 6].                
          Appellants argue that insertion of 1's into the shifter of Chu              
          does not make obvious the specific digital signal whose value
