ABSTRACT:
An IC including duplicated primary components which can be operated microsynchronously has at least one synchronization device for synchronizing asynchronous signals to the primary clock. An asynchronous signal intended for the primary components is routed via the synchronization device, synchronized and supplied to the inputs of the primary components. With duplicated asynchronous components, an output signal from just one asynchronous component is synchronized and is supplied to the primary components.
