A memory protection unit includes at least a first access control unit and a second access control unit programmed for controlling an access to a memory device. Further a method to operate a processing system comprising multiple processing devices and multiple memory protection units associated to the multiple processing devices. The access to the memory by a processing device is approved if first access control unit and second access control unit of the memory protection associated to the processing device approves the access and access is rejected if first access control unit or second access control unit rejects the access. The first access control unit is programmable by the associated processing device alone and the programming of the second access control unit is readable by an additional processing device which is to be used in a system with multiple programming devices, not the associate processing device.

Memory protection unit and method for controlling an access to memory device

A method for controlling the sequence of a plurality of functions which are executable on at least two interacting devices is provided, first of the functions being implemented on a first device and the second of the functions being implemented on a second device. A system for implementing the method is provided, including an administrative unit which controls a sequence of the functions in such a manner that it prevents a first function and a second function which interfere with one another from simultaneously running.

Sequencing control of simultaneously executed forbidden pairs of first and second functions on at least two interacting devices based on priority
