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.

Abstract: A communication system configuration has an annular design and includes multiple participants which are serially interconnected, one participant being configured as a master and the remaining participants being configured as slaves. The master is configured for transmitting a data packet to one or a plurality of slaves, and each slave has a shift register. The communication system includes a participant which has an external interface and is adapted for receiving data via the external interface from outside of the communication system to implement a debugging or a programming of one or a plurality of participants of the communication system or for transmitting data to outside of the communication system.

Abstract: A communication system which has a ring-shaped configuration and has at least two users. The users are connected to one another in series, one user being configured as the master and the remaining users being configured as slaves. The master is configured to transmit a data packet to one or multiple slaves. Each slave has a shift register. At least one user in the communication system includes a programmable hardware module, and at least one user in the communication system includes a memory arrangement. The programmable hardware module is configured so that it may be configured by reading out data of the memory arrangement.

Abstract: 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.

Abstract: A method is described for monitoring a data memory in which an error detection method is used to detect and/or correct incorrect data words stored in memory lines of the data memory, an address of the data memory at which a data word evaluated as incorrect by the error detection method is stored being written to an auxiliary memory and being made available to a checking program.

Abstract: A method and a circuit configuration are provided for generating a multiphase PWM signal. For this purpose a number of PWM generators are provided, which respectively have one counter, two comparators and one state memory, each PWM generator outputting a PWM signal, which represents a phase of the multiphase PWM signal, the PWM generators being coupled with one another via multiplexers such that the counters of the PWM generators that are coupled with one another are clocked identically.

Abstract: 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.

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: In a method is provided for evaluating an analog signal, which carries data on a rotational motion, the analog signal is read in by an A-D converter for evaluation and zero crossings of the analog signal are determined.

Abstract: A memory protection unit includes at least a first access control unit and a second access control unit programmed for controlling an access to a memory device. Further a method to operate a processing system comprising multiple processing devices and multiple memory protection units associated to the multiple processing devices, The access to the memory by a processing device is approved if first access control unit and second access control unit of the memory protection associated to the processing device approves the access and access is rejected if first access control unit or second access control unit rejects the access. The first access control unit is programmable by the associated processing device alone and the programming of the second access control unit is readable by an additional processing device which is to be used in a system with multiple programming devices, not the associate processing device.

Abstract: A method is described for transmitting data between participants of a serial, ring-shaped communications arrangement in which the participants are serially connected to one another, wherein a data packet is passed from a participant provided as a master to further participants provided as slaves, wherein the data packet is passed from slave to slave, and wherein address information of the data packet is altered by each slave.

Abstract: A method for serial data transmission from a transmitter to a receiver has the following steps: a) establishing at least one digital data word which is representative of a data value to be transmitted; b) establishing a pulse duration which is proportional to a non-negative integer represented by the data word plus a constant positive allowance; c) transmitting a pulse (IH, IM, IL) having the established pulse duration from the transmitter to the receiver; and d) detecting the pulse duration at the receiver and reconstructing the data word.

Abstract: A method and a device for controlling an internal combustion engine using at least two control units. One engine rotation is divided into a predefined number of subsegments of equal length. One or a plurality of subsegments are able to be combined in each case into one segment. Control data are calculated in all subsegments. Each control unit outputs the control data once per segment.
