Summary:1. Field of the Invention A method and system for synchronizing data streams and transferring control of resources between two processes in a graphics processor is described. The method allows for completion of pending operations of a first process in a manner that ensures the first process may be restarted without loss of data or process sequence. The processing pipeline is allowed to complete normal execution of all process operations required to reach a first process step that may be interrupted. The second process is initiated when the interruption of the first process is verified. Upon completion of the second process, the first process is reactivated at the next process step in sequence.
