ABSTRACT:
A method and apparatus for simultaneously displaying data from different sources. A data processing system includes a display unit, data processing units, and data diodes. The display unit has controls that are capable of generating control signals and the display unit is capable of simultaneously displaying the data from the different sources. The data processing units are arranged in a hierarchy of rankings. Each data processing unit is capable of accessing one of the sources. The data diodes are in the connections carrying control signals from the controls to data processing units and are in connections from one data processing unit to another data processing unit. Data is capable of moving only from a lower ranked data processing unit to a higher ranked data processing unit. Data is prevented from moving from a higher ranked data processing unit from a lower ranked data processing unit.
