Abstract
A system on a chip or storage device has a dynamic process for handling system events that are transmitted at varying transmission rates. This dynamic process is a hybrid mode of operation that tailors the use of time stamp information according to the dynamic flow of events that are submitted in the system. Relative time stamps can be used along with explicit time stamps. Periodic wrap around events which use relative time stamps based on the periodic wrap events may be suppressed when there were no events between consecutive wrap around events. When an asynchronous event occurs during the suppression, the event is identified with a high precision time stamp (HPTS) rather than a relative time stamp. The periodic wrap around events can be re-initiated after the HPTS event is stamped.
