Abstract:
A method of monitoring a data processing circuit which includes at least two data processing systems, which are mounted on a joint chip and connected by data lines, wherein the data processing systems jointly produce data words and a data word sequence which are transmitted at predetermined times to a monitoring circuit that is mounted on a separate chip, and are checked by the monitoring circuit with respect to the contents and time of appearance of the individual data words wherein parts of the individual data words of the data word sequence are produced in each of the data processing systems, wherein the partwords are put together in one of the data processing systems to a complete word, as a whole, and the other data processing system governs the transmission of the complete data word, from the processing system which joins the words to the monitoring circuit wherein the partwords are produced according to different algorithms in the data processing systems.
