This article describes a method for decoding any prefix code where the number of source symbols does not exceed some maximum and relates to a prefix code which has the property that no code word is a prefix of any other code word. The advantage of this approach is that it is table-driven: to change the code one merely reloads the table. The same hardware suffices for the decoding and does not need to be changed. In contrast, traditional coding approaches generally require a redesign of the hardware.
