Event-driven performance monitors have found widespread use since they can give valuable information on the performance of various pieces of data processing hardware. Typically, an event which occurs will cause a count to be accumulated, indicating the length of time that particular event spans on a cumulative basis. In its simplest form, the performance monitor merely requires storage capacity in the form of a counter and a gating circuit for gating clock pulses into the counter under control of the event, the count accumulated in the counter being an indicia of the total time that the event recorded exists.
