Abstract: A method for operating a computing unit in a safe operating mode. The method includes reading an activation instruction for activating a safe operating mode, activating the safe operating mode in response to the activation instruction which has been read; in the safe operating mode, reading instructions and calculating a current check value in each case from a current instruction to be executed and a previous check value; and in the safe operating mode, checking the current check value at least once.

Abstract: A method for accessing a data block, stored in a memory unit of a computing unit, of a number of data blocks. The method includes: activating a safe operating mode of the computing unit; in the safe operating mode of the computing unit, accessing the data block; if the access is a read access, reading data from the data block and subsequently writing the data into the data block; if the access includes a write access, reading first data from the data block, removing the first data from a check value associated with the data block, writing second data into the data block, adding the second data to the check value associated with the data block; and checking the check value associated with the data block.

Abstract: A method for checking data in a storage unit of a system on a chip; a monitoring unit, which may be activated or deactivated by the system on a chip, being implemented in the system on a chip. When it is activated, the monitoring unit storing error correction codes for executing error correction methods, in the storage unit, such that, for a predefined number of data blocks of the storage unit, in each instance, a data block including an associated error correction code is stored. When access to data in the storage unit is intended to take place, the monitoring unit addresses the respective data and an associated error correction code and checks the addressed data prior to the respective access, using the addressed error correction code, and correcting them when required.

Abstract: A circuit configuration for a data processing system for predicting a coordinate for at least one operation to be carried out is provided, the prediction being connected to at least one input signal and being a function of a predefined first time value and at least one predefined first value which represents another physical variable. Upon each change of the at least one input signal, a second time value is calculated in each case from the first value, and to subtract the first time value from the second time value to form a third time value, and/or to calculate a second value from the first time value, and to subtract the first value from the second value to form a third value, in order to determine from the third time value and/or the third value a state in which the at least one operation is to be carried out.

Abstract: A method for transmitting frames containing data between users of a ring-shaped communication system which has a master and at least one slave as users. Each user has at least one interrupt register, and one field of the at least one interrupt register is associated with an interrupt request and includes a value for an interrupt bit. An interrupt request which includes the interrupt bit is transmitted to the master by a slave in a frame designed as an empty frame. In addition, the empty frame has a toggle bit for all slaves which indicates the state of an interrupt request.
