A method for operating a microcontroller. The microcontroller includes a plurality of resources, a plurality of virtual machines being executed in the microcontroller, a coordination unit being superordinate to the plurality of virtual machines. Access information concerning accesses of the plurality of virtual machines to the plurality of resources is stored in the coordination unit. In the event that one of the virtual machines requests a reset of one of the resources, the coordination unit checks on the basis of the access information, which of the virtual machines are accessing this resource. The coordination unit determines on the basis of this check, whether the resource will be reset or whether a substitute measure will be taken.

Method for operating a microcontroller

A circuit arrangement for a data processing system is configured to process data in multiple modules. The circuit arrangement is configured to provide a clock as well as a time base and/or a base of at least one further physical quantity for each of the multiple modules. The circuit arrangement also comprises a central routing unit, which is connected to several of the multiple modules. Via the central routing unit, the modules can periodically exchange data based on the time base and/or on the base of the at least one further physical quantity. The several modules are configured to process data independently of and in parallel to other modules of the several modules.

An emulation system and emulation method for a no longer available microcontroller, having a supplyable microcontroller and emulation software able to be run thereon, and having an interpreter, the emulation software forming a software layer between the hardware of the available microcontroller and an operating software of the no longer available microcontroller, and the software being adapted in such a way that the hardware of the available microcontroller in conjunction with the additional emulation software behaves like the hardware of the no longer available microcontroller, and the interpreter is adapted in order to represent address, code and data information of the operating software of the no longer available microcontroller to functionally equivalent address, code and data information of the available microcontroller.

A companion chip for a microcontroller has a microprocessor bus domain and a peripheral module bus domain, which are connected to each other via a bus bridge. The microprocessor bus domain includes at least one microprocessor core, and the peripheral module bus domain includes at least one global time-management module as well as modules for communication with the outside world and for signal processing. The companion chip further includes at least one FIFO module for transmitting data within the chip, and between the chip and the microcontroller, and a management module connected to the FIFO module, which ensures the consistency of the data by associating a respective time value and/or an angle of rotation.

A method of protecting a microcomputer system against manipulation of data stored in a memory arrangement of the microcomputer system, in particular a control program stored there. Checking mechanisms are executed at preselectable points in times to check for manipulation of the data. To permit effective blocking of manipulated data stored in the memory arrangement, new data is stored at least partially in a volatile memory, in particular in a random access memory, in reprogramming or new programming of the memory arrangement, the checking mechanisms are executed and the portion of the new data stored in the volatile memory is copied to the memory arrangement if no manipulation of the new data has been detected.
