32. A method, comprising: storing a first group of first code words in sequential locations of a memory; storing in an address table the respective starting location of the first group and the respective lengths of at least one of the first code words; and storing a second group of second code words in sequential locations of the memory, each second code word having a same length, a combination of each first code word with a corresponding second code word representing a respective software-program instruction.
