          Application 08/160,111                                                      


          left rotating said second multibit digital signal an amount                 
          corresponding to said rotate control signal and supplying said              
          left rotated second multibit digital signal to said second                  
          data input of said arithmetic logic unit;                                   
               a third data source supplying a third multibit digital                 
          signal; and                                                                 
               a mask generator having a data input connected to said                 
          third data source and a data output connected to said third                 
          data input of said arithmetic logic unit, said mask generator               
          generating a multibit digital mask signal corresponding to                  
          said third multibit digital signal.
