Abstract: A redundant two-processor controller having a first processor (1) and a second processor (1) for the synchronous execution of a control program. The controller having at least a first multiplexer (70, 91) for optionally connecting at least a first peripheral unit (72, 95) to be actuated to one of the two processors (1, 2), and at least a first Comparison unit (70, 91) for monitoring the synchronization state of the two processors (1, 2) and for detecting a synchronization error. A restoration control unit (44) is designed to monitor the execution of at least one test program by the two processors (1, 2) after the occurrence of a synchronization error and to evaluate the test results, and which is designed to configure at least the first multiplexer (70, 91).

Abstract: The invention relates to a circuit arrangement for forming a digital interface comprising a digital data bus, which exchanges data when microprocessor systems are connected. The data exchange can be effected bidirectionally. On transmission of data the circuit arrangement generates as bus master a bus clock speed and operates on receipt of data as a bus slave in accordance with the received clock signal. The circuit arrangement comprises at least one FIFO memory for receiving data.

Abstract: A checking method in which serial data protected by check data are transmitted via a serial data bus from a transmitter to a receiver, the receiver then conditions the data and compares them with the transmitted check data in order to recognize transmission errors, wherein the transmitter bases the production of the check data and the receiver bases the conditioning of the data on the same check data formation method, wherein the check data formation/conditioning is performed using error recognition hardware, wherein the region of the receiver contains not only the error recognition hardware but also error recognition software which are used to additionally check the received data, and wherein also an error in the transmitted data and/or check data is caused by a transmitter-end error stimulation. A transmission and reception circuit for carrying out the above method and also the use thereof is also disclosed.
