Abstract
A system for accumulating data relating to performance parameters of a data communication system is provided in order to determine average values of these parameters. The system comprises multiple registers used for calculating average values of particular performance parameters, such as bus latency, interrupt latency, receive service routine time, and receive frame copy time. Each of the registers contains an event counter and a timer. The event counter increments upon occurrence of an event relating to the performance parameter accumulated by the corresponding register. The timer is activated by the occurrence of the event, and increments at a predetermined rate until the event comes to an end. The timer resumes incrementing when the next event occurs. As a result, the CPU is enabled to determine an average value of a particular parameter per an event relating to this parameter.
