An architecture of an ignition and/or injection managing system for an internal combustion engine, of the type structured to cooperate with an electronic engine control unit. Also included is an electronic device architecture for determining the operating phase of an internal combustion motor, based on an input signal issued from a sensor of a phonic wheel associated with the motor camshaft, so as to release the electronic motor control unit from monitoring the phonic wheel signal, in order to lighten its computational load, and to enable the processing of the signal issuing from a variety of the phonic wheels. The device has the task of calculating the angular position of the drive shaft by analyzing the signal transmitted by the tone wheel of the drive shaft. A module is provided that is capable of emitting an interrupt signal toward the control unit on the basis of received signals.
