  • Method for executing, within a multitasking onboard system, an application timed according to a plurality of different time domains including interruption management
    Patent number: 9785587
    Abstract: A method for executing an application in a multitasking system is provided. The application is composed of at least one task for which the temporal triggering is specified in a first temporal reference frame that is asynchronous relative to the physical time, called first external clock domain, defined by a synchronous basic clock with changes of state of a peripheral device of the system. The method comprises a set of steps executed by the system upon reception of an occurrence of an interrupt in order to render the execution of the task deterministic or quasi-deterministic.
    Type: Grant

  • Method for the deterministic execution and synchronization of an information processing system comprising a plurality of processing cores executing system tasks
    Patent number: 9128752
    Abstract: An information processing system includes two processing cores. The execution of an application by the system includes the execution of application tasks and the execution of system tasks, and the system includes a micro-kernel executing the system tasks, which are directly linked to hardware resources. The processing system includes a computation part of the micro-kernel executing system tasks relating to the switching of the tasks on a first core, and a control part of the micro-kernel executing, on a second core, system tasks relating to the control of the task allocation order on the first core.
