A method and device for the synchronization of processes, a first signal being sent by a clock-giving processor, the first signal having, in an alternating manner, first edges having a first direction and second edges having a second direction opposite the first edge, a temporal distance between at least one of the first edges and at least one of the second edges being determined as a function of a state of a counter in the clock-giving processor. A method for the synchronization of processes, a first signal being received by a clock-receiving processor, the first signal having, in an alternating manner, first edges having a first direction and second edges having a second direction opposite the first edge, a state of a counter in the clock-receiving processor being determined as a function of a temporal distance between at least one of the first edges and at least one of the second edges.
