Abstract
This system determines the operation of data transfer means by direct memory access by a task scheduler in charge of process context changes, the system including deterministic means for establishing and suspending the data transfers of memory data initiated before, but not terminated during, the contextual changes, and for resuming the data transfers during the return to the corresponding initial context, in order to give each process full and exclusive access to the means of transfer.
