Abstract
An apparatus includes a global synchronization interface and multiple modules. The global synchronization interface includes a global synchronization driver for driving a global synchronization signal. The modules include corresponding local synchronization interfaces, each local synchronization interface having a local synchronization driver for driving a local synchronization signal. In a local mode, the modules ignore the global synchronization signal and synchronize corresponding operations according to the local synchronization signal and a global reference signal. In a global mode, the modules ignore the local synchronization signal and synchronize the corresponding operations according to the global synchronization signal and the global reference signal.
