ABSTRACT:
A self-monitoring system is comprised of a main processing unit incorporating a computer and an interrupt processing unit which regularly interrupts the operation of program by the main processing unit. Each unit contains a counter which counts the processing time of the associated unit and is initialized by the other unit. The two units thereby check the operation of each other by monitoring the numbers counted by these counters.
