The invention is directed a method for transferring at least one datum between a real-time task producing a datum and a real-time task consuming said datum. The method may include, in response to initiation of a transfer of a datum by a current instance of an initiating task: creating at least one DMA descriptor describing the DMA transfer expected for said datum; inserting DMA descriptors into a list of descriptors awaiting processing by a DMA controller, said DMA descriptors being inserted in a manner sorted based on a sorting criterion relating to a visibility date of the data and/or a temporal behavior of the tasks; processing the descriptors on the list of DMA descriptors by executing DMA requests; and executing the following instance of the initiating task based on termination of the processing a predefined set of DMA descriptors on the list of descriptors.
