Zusammenfassung:A method for dynamically assigning memory bandwidth to multiple processor units, which are connected via a data connection to a shared memory unit. In an initialization phase, each of the multiple processor units are assigned an initial value of a usable memory bandwidth, and a permissible range for a mean usage of the memory bandwidth is determined. Subsequently, the assigned memory bandwidths are checked repeatedly and adjusted if needed, a present value of a mean usage of the memory bandwidth by the multiple processor units being determined, and, if this present value is outside the permissible range, the values of the usable memory bandwidth are adjusted for at least a part of the multiple processor units.
