Abstract
In the field of systems for the synchronization of modular electronic circuits, a system is provided for the coordinated activation of the modules. This system includes synchronization cells that have their pace set by a primary clock signal and deliver secondary clock signals controlled intermittently by the enabling signals to respectively activate the modules. The cells lock the state of each enabling signal associated with a regulator for regulating the periodicity of the change in state of each secondary clock signal and coordinating the changes in states of the secondary clock signals with one another. The system can be advantageously applied to electronic circuits having very high frequency data processing modules, especially those providing for the multiplexing of the transmissions of data carried out by each module.
