There is provided a register system of a microcomputer having a register that includes at least one register bit and having an additional storage arrangement allocated to the register and on which the data content of the register is able to be intermediately stored. To reduce the computing time for saving the data content of the register, while keeping the silicon surface required for the register system as small as possible, the additional storage arrangement includes at least one shift register having at least two shift register cells, the content of an arbitrary shift register cell being transferable into a register bit, and, conversely, the content of a register bit being transferable into an arbitrary shift register cell.

A method and a device having a processor module for controlling operating sequences, in particular in an engine control unit in a motor vehicle, peripheral elements being selected by a processor module having a predetermined number of select interfaces by select signal output over these select interfaces, and instructions being transmitted to the peripheral elements over at least one information interface of the processor module. Selection identifiers are assigned to the instructions and transmitted together with them. Thus, a selection of peripheral elements is made by a select signal and a selection identifier.

A circuit arrangement for a data processing system is configured to process data in a plurality of modules. The circuit arrangement is configured such that each module is provided with at least one clock pulse, a time base and a base of at least one additional physical variable. The circuit arrangement also comprises a central routing unit to which the plurality of modules are coupled and via which the plurality of modules can periodically exchange data amongst themselves, based on the time base and/or the base of other physical variables. Each module is configured independently and parallel to other modules of the plurality of modules in order to process data. The circuit arrangement is employed in a corresponding method.

A microcontroller for a control unit or a vehicle control unit, includes a central processing unit (CPU), at least one interface-unspecific input module, at least one interface-unspecific output module, at least one routing unit and at least one arithmetic unit for processing interface-specific information. The microcontroller is configurable so that the at least one interface-unspecific input module, the at least one interface-unspecific output module, the at least one routing unit and the at least one arithmetic unit for processing interface-specific information fulfill the functions corresponding to one of multiple serial interfaces, in particular of SPI, UART, LIN, CAN, PSI5, FlexRay, SENT or Ethernet. In addition, the arithmetic unit is configured to generate an entire output message frame from the second payload data as output data and to transmit the same to the interface-unspecific output module.

A control device in a vehicle includes a unit for calculating, during operation of the vehicle, on the basis of at least one input variable ascertained during operation, at least one output variable for a control system of functions of the vehicle. The control device performs the calculation of the output variables using a Bayesian regression of training values ascertained, before operation, for the output variable and the input variable.

A method of detecting manipulation of a programmable memory device of a digital controller for a motor vehicle is described; data and control programs for operation of the controller and for control/regulation of certain functions of the motor vehicle can be stored in the memory device. To permit especially reliable detection of manipulation in the simplest possible way, in conjunction with each programming/reprogramming operation of the programmable memory device, information regarding the programming/reprogramming operation is stored in a separate memory area of the memory device where only reading and programming are possible, and in order to detect manipulation, the content of the separate memory area is read out and compared with given information.
摘要:
To detect a power failure in a volatile data memory containing useful data units and test data units associated with the useful data units, the associated test data unit is also read when the useful data unit is read-accessed, and a decision is made as to whether the useful data unit is corrupted based on the test data unit. A power failure is identified when at least two read useful data units within a predefined number of successive read accesses are found to be corrupted.
摘要:
A method and apparatus for monitoring an electronic control system, where code of a memory is, in a context of ongoing instruction accesses, transferable via a word line out of the memory to a control unit having a specific word width encompassing code of a plurality of memory cells of the memory and where an additional datum is created in each case for the code of a word width and is storable in the memory, may include an arrangement that, outside the ongoing instruction accesses, checks an entire code of the memory by selecting for each word width a single memory cell to thereby activate a complete word line, that creates a check datum from code of the complete word line, and that compares the check datum with the stored additional datum.
