Abstract: A signal-processing system, e.g. for a telephone exchange, comprises n modular processing units each including a pair of identical microprocessors operating in parallel on binary signals arriving over an internal bus, only one microprocessor of each pair being enabled to transmit outgoing messages to that bus while the other operates as a dummy. The two microprocessors are interlinked by a correlating connection enabling verification of their correct operation in response to microinstructions read out from respective microprogram memories thereof under the control of a common clock. A momentary divergence, resulting from a relative lag in the response of one microprocessor to an asynchronously arriving signal bit, results in a delay of the microprogram by one clock cycle to permit resynchronization; longer-lasting disparities lead to a deactivation of the microprocessor pair and to the emission of an alarm signal.
