Abstract: A method for describing contents of a memory and for describing a transfer of contents of a memory or memory area of a vehicle control unit includes the following steps: providing a description of segments of an area of the memory, including its properties, the segments being designed as physical segments and/or logical segments and/or functional segments; providing a definition of interfaces and/or methods for transferring memory contents of, from and/or between the segments, the interfaces and/or methods describing the manner, time and other limiting conditions of the transfer.

Abstract: A motor vehicle control unit, in particular an engine control unit, includes a processor, a first interface for the communication with functional units of the motor vehicle and at least one second interface, which is combined with the processor in a sub-assembly.
