Abstract

The invention is an apparatus which utilizes relatively few conductors to provide fail-safe communication between multiple electrical subsystems and a redundant pair of data processors. This is accomplished by including two first-in, first-out memory units within each electrical subsystem, and utilizing these memory units to send the output data from the electrical subsystems on a pair of parallel data buses to a redundant pair of data processors, which then perform error tests on the data to ensure its integrity.
