Abstract
An event occurring in a graphics pipeline is detected and counted at the location of its occurrence using an event detector and a local counter. The event count maintained by the local counter is reported asynchronously to a global counter. The global counter is configured to be of higher precision than the local counter and is positioned at a place that is convenient for reporting the events, e.g., at the end of the graphics pipeline.
