   Brain dead easy: 1 table of 1024 entries each 12-bits wide,   
                    1 table of 4096 entries each 10-bits wide,   
   isolate the 10-bit field, LD the converted value.   
   isolate the 12-bit field, LD the converted value.   
      
   Other than "crap loads" of {deMorganizing and gate optimization}   
   that is essentially what HW actually does.   
      
   You still need to build 12-bit decimal ALUs to string together
