Abstract
An application designed for the current version of a system runs at a standard clock frequency of a current version of the system. Running the application at the standard clock frequency includes synchronizing operation of a processor of the current version of the system with the standard clock frequency. An application designed for a different version of the system characterized by a different standard clock frequency runs at a second clock frequency that is different than the standard clock frequency. Running the application at the second clock frequency includes synchronizing operation of the processor of the current version of the system with the second clock frequency.
