A method for monitoring the execution of a program executable on at least one microprocessor of a micro controller using a debug logic of the micro controller, with an exception, particularly an interrupt of the program execution, being triggered by the debug logic upon access to a specific address range during the program execution time. In order to provide monitoring of the execution of a program, executable on a microprocessor, for faults, which is particularly reliable yet conserves resources as much as possible, it is suggested that the debug logic be configured by the microprocessor and that an exception routine be executed by the debug logic after an exception has been triggered during the program execution time. The debug logic is advantageously configured during the startup of the micro controller. Preferably, the micro controller is reset and started up again and the monitored program is initialized during the execution of the exception routine.

A memory arrangement is provided, which has a programmable memory and a first buffer memory associated with the programmable memory, to which buffer memory, in the case of a command access, at least one command following the accessed command is written. A second buffer memory may also be provided, to which buffer memory, in the case of a data access, at least one datum following the accessed datum is written. Also provided is a method for reading from a memory arrangement during program execution, wherein presence of a command access or a data access recognized, and a command following the accessed command is written to a first buffer memory and a datum following the accessed datum is written to a second buffer memory. Thus, in this manner, a separate buffer memory is described for data accesses, and thus the content of the buffer for command accesses is not overwritten or destroyed when data accesses occur during the program execution.

A method for protecting a microcomputer system against manipulation of data stored in a storage arrangement of the microcomputer system, in particular for protecting a program stored in the storage arrangement. The microcomputer system includes a microcomputer assigned to the storage arrangement, the microcomputer accessing the storage arrangement for the purpose of processing the data, i.e., the program. In order to prevent the manipulation of data in a microcomputer that does not have an internal memory but rather accesses an external storage arrangement and processes the stored data, it is proposed that before the storage arrangement is accessed, an individual identifier be assigned to the or to each allocated microcomputer or to the storage arrangement that a comparison code be generated as a function of the individual identifier and be stored in the storage arrangement, and that, before or during the operation of the microcomputer system, a security code be generated as a function of the individual identifier and be compared with the comparison code.

A system for controlling operating sequences, in particular in a motor vehicle, is described. The system contains program modules for controlling the operating sequences, and the program modules themselves and/or the program modules in their totality are divided into a hardware-dependent portion and a hardware-independent portion, so that the hardware-dependent portion and the hardware-independe+nt portion exchange physical variables.

A memory element and a device having a processor and a memory element, the memory element being positioned outside of the processor and being connectible to a processor via address and/or data lines, the address and/or data lines are each configured in an LVDS structure having corresponding drivers and receivers, and the drivers and receivers each being integrated in the memory element or in the processor.

A Method and an apparatus for providing control parameters to or within a control system for controlling a fuel injection system are described. The method is characterized in that a plurality of control parameters is transmitted to storage means ( ) within the control system by transmission means ( ). The transmitted control parameters are stored within the storage means ( ). Selection parameters are transmitted to selection means ( ) within the control system by transmission means ( ). Stored control parameters are selected in accordance with transmitted selection parameters by the selection means ( ). And the selected parameters are utilized for controlling elements within the control system. The apparatus is in particular eligible for usage with a inventive method and is characterized in that a control unit (D) and an activation IC (E) are connected to each other by transmission means ( ). Storage means ( ) are implemented in the activation IC (E). And selection means ( ) are implemented in the activation IC (E).
