Abstract

A system and method for generating a timestamp without processor core execution stall are provided. For example, the method includes generating, using a first processor core, a timestamp. The method also includes preventing, using the first processor core, a second processor core from accessing the timestamp for a minimum time granularity interval. The time granularity interval provides a delay such that the timestamp generated by the first processor core is earlier in time than a second processor core timestamp.
