Abstract
A method of encoding data values where the data values are arranged into words, each word having a plurality of input values and one or more padding bits. A word is encoded by determining whether more than half of the bits in a portion of the word are ones, where the portion may be some or all of the bits of the input values in the word, and in response to determining that more than half of the bits in the portion are ones, inverting all the bits in the portion and setting a corresponding padding bit to a value to indicate the inversion.
