Abstract
The method embodying the invention comprises management by a coprocessor of the time slicing, from a pre-established frame, of the processing cycle of the processor, into slices of possibly different durations, of the allocation of the time slices to the different functions installed according to one or plural pre-established layouts, of the saving at the end of the machine context slice of the function being processed, this with a view to resuming this function during the following slice associated with it and of the loading, at the start of a new slice, of the machine context linked with the activating of the function associated with this slice and which was previously saved at the end of a previous slice corresponding to this function. The invention applies to the optimizing and security of real-time management in modular avionics architectures.
