DATA PROCESSING ARRANGEMENTS HAVING CONVERTIBLE MAJORITY DECISION VOTING

摘要

A triplicated data processing arrangement has majority decision elements between the different portions of each processor. The arrangement is provided with the facility that it can be divided into an independent processor and two remaining processors by the application of a control signal to the majority decision elements. The two remaining processors will still apply data signals to the majority decision elements in the normal manner while the independent processor is tested in isolation without affecting the operation of the remaining system.
