Abstract: This method for implementing a partitioning during the execution of software applications on a platform comprising a multicore processor having several separate cores, is implemented by an electronic implementing device.It comprises a step for switching between the execution of a current set of software application(s) on a plurality of cores and the execution of a subsequent set of software application(s) on the plurality of cores, carried out in a synchronous manner on said plurality of cores, the step of synchronous multicore switching including one or more actions among a first group of actions consisting of: waiting, synchronized over the plurality of cores, for uninterruptible process(es) of the current set of software application(s) to finish running; and purging all memory resource(s) associated with the current set of software application(s).

Abstract: A method and device for monitoring an avionics software application via its execution duration, related computer program and avionics system are disclosed. In one aspect, the method, executed on a platform hosting an operating system, is implemented by an electronic monitoring device. The avionics software application includes one or several software processing operations to be executed, the platform is configured to be on board an aircraft. The method includes: monitoring the execution duration of the avionics software application, through the verification, upon expiration of at least one predefined execution times, of the completion of the execution of at least one software processing operation of the avionics software application; and updating a status of the avionics software application based on the monitoring of the execution duration of the avionics software application.
