Abstract

An electronic system comprises an initiator module and a target module addressable by the initiator module. The initiator module is activated by edges of an activation signal generated from a first clock signal having a frequency. A control module is activated by edges of a second clock signal having a frequency, which is at least twice as large as the frequency of the first clock signal. The control module is constructed so as, in response to an request for access to the target module, initiated by the initiator module on an active edge of the activation signal, to set a signal for blocking the activation signal before the next edge of the latter, and to reinitialize the blocking signal on the first active edge of the first clock signal which follows the indication by the target module that the processing of the request is terminated at the target module.
