Abstract
Disclosed is a universal profiling device operable to simulate a performance monitoring unit for a heterogeneous system. The universal profiling device includes a main circuit and a storage circuit. The main circuit is configured to execute at least one of multiple steps including an active data collection step and a passive data collection step. The active data collection step registers a callback function for an event of a designated object according to predetermined setting or user setting, and actively calls the callback function to obtain information of the event. The passive data collection step registers the event of the designated object according to the predetermined setting or user setting and thereby receives the information of the event without requesting the designated object, wherein the information of the event is stored in the storage circuit.
