Abstract
A circuit is described comprising a first () and a second circuit module () and a synchronization module (). The first and the second module are mutually asynchronous, and are coupled by the synchronization module. The synchronization module () comprises: a transfer register () for storing data which is communicated between the two circuit modules, a control circuit () for controlling the register in response to a respective timing signal (St, St) from the first and the second circuit module, the control circuit comprising a control chain for generating a control signal (CR) for the transfer register (). The control chain includes at least: a repeater () for inducing changes in the value of the control signal, at least one edge sensitive element () for delaying a change in the signal value until a transition in a selected one of the timing signals is detected.
