Abstract: An aircraft control system including transducers connected by interface units to an avionics network, such as an AFDX network. Each transducer is directly connected to an interface unit local to the transducer. Each interface unit is a configurable unit and has a signal processing module converting data to a format suitable for transmission over the network. Each interface unit may be configurable, via software commands, to operate in an application session mode, a data-loading mode, or a maintenance mode. Each interface unit may be directly associated with one of the software applications of the aircraft control system. The network may include a lower bandwidth part where data communication is conducted over sampling ports only. Interface units may be configured or installed using a plug and play method.

Abstract: A method for managing access to a shared resource in an electronic system including a control unit and the shared resource. The control unit is intended to execute applications that are candidates for access to the shared resource. The method uses a calendar of periods of equal duration, each assigned to just one of the applications, to define a temporal distribution of access to the shared resource, and penalty indices associated with each of the applications. The method includes steps for conditionally processing the access requests transmitted by the applications according to their penalty indices. Thus, each application is prevented from accessing the shared resource when the quota assigned thereto is reached, which makes it possible to limit the encroachment of an application that is executed on the access quotas for accessing the resource that are assigned to the other applications.

Abstract: The avionic system of an aircraft includes a set of avionic computers and a switch associated with each avionic computer. For each avionic computer of the set of avionic computers, the avionic system includes a communication link between the switch associated with this avionic computer and each of the switches associated with the other avionic computers. Each switch is configured such that it routes the data frames received on its input ports to its output ports in a manner predefined only on the basis of the input ports on which these data frames are received. The various switches are configured such that, when an avionic computer sends a data frame, this data frame is transmitted to all of the other avionic computers.
