A method for encoding and decoding of digital data, in particular of processed data in a microprocessor unit

摘要

The invention relates to a method for encoding digital data, in particular of processed data in a microprocessor unit. In the method according to the invention, for a respective data word (a, b, c) a series of successively to be coded data words a parity code (p (a), p (b), p (c)), based on the data of the respective data word (a, b, c), calculated. Furthermore, the respective data word (a, b, c) in the series with the aid of the preceding data word (a, b, c) is modified, wherein the modified data word (aa, ba, ca) and the parity code (p (a), p (b), p (c)) the encoded data word (ac, bc, cc) and the encoded data word (ac, bc, cc) in the series with the aid of the preceding data word (a, b, c) is travelling behind.
