A method for determining check sums for a buffer memory for a processor, the method including a step of reading in a data unit of the buffer memory marked as changed by an access of the processor, a step of ascertaining a check sum for the data unit using a check sum unit of the buffer memory and a step of supplementing the data unit with the check sum and marking the data unit as changed with a valid check sum.

Method and device for determining check sums, buffer memory and processor

A method for monitoring a drive-by-wire system of a motor vehicle, including: temporally offset reading in of at least two input values of an input quantity of an operating element of the motor vehicle; ascertaining a change over time or rate of change over time of the input quantity from the at least two read-in input values; determination of a monitored quantity for the motor vehicle operation from the change over time or rate of change over time; selection of a monitoring function on the basis of the monitored quantity; monitoring of the monitored quantity for the ascertained motor vehicle operation by the monitoring function.

Method for monitoring a drive-by-wire system of a motor vehicle

A method for operating a microcontroller, where access rights of processes executed in the microcontroller to different memory areas are stored in a memory protection unit, includes, in the course of a simulation mode, a first process carrying out an access attempt to a certain memory area in a certain manner in the name of a second process; the memory protection unit transferring access rights of the second process for the certain memory area to the first process upon the access attempt. The access rights are read out by the first process and the simulation mode is terminated. The access attempt is preferably thereupon terminated and an access is not carried out according to this access attempt by the first process.

Method for operating a microcontroller

A memory protection unit including hardware registers for entering address tables, a configuration memory for storing the address tables, a preconfigured hardware logic for managing the configuration memory, a data connection between the configuration memory and the hardware logic for loading the hardware registers, a first interface for controlling the loading by a computing core, and a second interface for writing to the configuration memory by the computing core.
