Abstract:
In an apparatus for controlling the access operation by a plurality of data processing devices to a memory, each data processing device (10, 11, 12) is assigned a respective address region which indicates the part of the addresses of the memory (13) which the respective data processing device can access. A control device (21) blocks an access operation by a data processing device to the memory (13) if the access operation address is not located in the address region which is assigned to the respective data processing device (10, 11, 12).
