For coding and decoding data, the data to be coded and the decoded data being stored in a memory (1), a single data coding and decoding means (4) is used. The coding and decoding means is initialised in coding mode, and the passage of data to be coded from the memory (1) to the coding and decoding means (4) is controlled, or the coding and decoding means is initialised in decoding mode, and the input of coded data into the coding and decoding means (4) and the passage of decoded data from the coding and decoding means to the memory (1) are controlled.
