摘要:
In order to monitor a data processing circuit containing two (or more) microprocessors (MP1, MP2) on a shared chip and interconnected by data lines (1), said microprocessors generate data in common which form a data word sequence and are transmitted to a monitoring circuit (4) at predetermined times. The monitoring circuit (4) is on a separate chip (IC2). The data words of the data word sequence are monitored by the monitoring circuit according to the content and time of occurrence of the individual data words. It is an advantage to compose the individual data words of partwords generated by different algorithms.
