A data processing system comprises a processor (1), a data memory (3), which is structured in a number of useful data blocks (3-1, 3-2, ..., 3-15) and test data blocks (3-16, 3-17, 3-18), and comprises a data test circuit (7) for testing one of each useful data blocks, which is accessed by the processor (1), for a freedom from errors using test data stored in a test data block assigned to this useful data block. In the event an error has been determined by the data test circuit (7) in a useful data block called up by the processor (1), a data correction circuit (7) is provided for blocking the use of the faulty useful data block by the processor (1) until the error has been corrected. |
