Abstract
A method for executing tasks of a real-time application on a multitasking computer, steps including: defining time-windows, each associated with the execution of processing operation of task of the application, allocating to each processing operation having time-window, time-quota and time-margin, time allocated to processing operation by time-quota and time-margin being shorter than duration of time-window of processing operation, during the execution of application, activating each processing operation at the start of time-window with which it is associated, on expiry of time-quota of one of processing operations, activating an error mode if the execution of processing operation has not been completed and, if error mode is active for one of processing operations, executing an error handling operation for processing operation, during remaining time allocated to processing operation by time-quota and time-margin.
