Abstract

Generating monotonically increasing time-of-day values in a multiprocessor system is provided. Synchronization impulses are received by a processor of the multiprocessor system, and an execution of a read instruction of a time-of-day value within a processor of the processors is refused, if the execution of the read instruction of the time-of-day value is requested after a predefined time after a synchronization impulse of the synchronization impulses, and if a trigger signal, indicative of new data received by a related memory system, has been received after the predefined time, wherein the memory system is external to the processor.
