ABSTRACT:
An electronic system comprises an initiator module and a target module addressable by the initiator module, and an interface and control module for interfacing between respective communication protocols of the initiator module and of the target module. The interface and control module is constructed to set a composite instruction detection signal in response to the detection of a composite instruction executed by the initiator module, which composite instruction detection signal is used for the interfacing. The interface and control module is constructed to detect a composite instruction executed by the initiator module when, at a determined clock cycle of the initiator module, a change of the elementary operation executed by the initiator module is detected with respect to the previous clock cycle of the initiator module, while, at the same time, a signal for selecting the target module which was active is kept active.
