2-out-of-3 selecting facility in a 3-computer system
This patent describes a 2-out-of-3- selecting facility for a 3-computer system in which all computers process the same information in parallel, and in which a result is delivered for further processing only if at least two of the computers have arrived at this result. The facility comprises an output port (A1...A3) in each of the computers and a comparison data input port (E1...E3) in each of the computers which is connected to the output ports of the other two computers for the transfer of the results produced by these computers. It comprises comparison circuitry in each of the computers for comparing the result produced by it with the results produced by the neighboring computers and providing a corresponding comparison indication, to a majority voting circuit (MS). The circuit is connected to receive the comparison indication depending on the comparison indications from all computers. The computers have outlet ports and the facility has two separate data output channels.
