== Overview ==

The bus-invert encoding technique uses an extra signal (INV) to indicate the "polarity" of the data. Having a bus-invert code word INV@x where @ is the concatenation operator and x denotes either the source word or its [[ones' complement]], the bus-invert decoder takes the code word and produces the corresponding source word. If the INV signal is 1, the result is oneones's complement of x, otherwise it is x.
