1. An uncontrolled data processing device (UDPD), comprising:

  • a display;

    a processor; and

    memory comprising instructions when executed by the processor, cause the processor to determine whether a safety critical application (SCA) is functioning properly on the UDPD, comprising;

    initiate a computation using reference computational inputs by the SCA to derive a computation test result;

    retrieving a corresponding reference computational data stored in memory of the UDPD;

    compare the derived computation test result with the retrieved corresponding reference computational data; and

    determine whether the SCA is functioning properly on the UDPD based on the comparing.
