Abstract: An arrangement comprises a memory device for storing data, and a program-controlled unit with a memory interface for reading data out of the memory device. The memory device is supplied with a first clock signal and transmits the data at the rate of a second clock signal, and the second clock signal to the memory interface when the memory interface performs a read access. The first clock signal is also supplied to the memory interface which generates from this signal a third clock signal which has the same frequency as the first and second clock signal but a predetermined phase shift with respect to the second clock signal. The memory interface accepts the data with the rising and/or falling edges of the third clock signal or the inverted third clock signal, and the third clock signal is also used as clock signal by other components of the memory interface.

Abstract: An arrangement with a memory for storing data has a first memory for storing data, switching devices which stipulate whether access to the first memory involves output of the data stored in the first memory or other data, and a second memory for storing the other data. The arrangement is distinguished in that it contains a third memory (103, 203, 310), which is addressed by the address (A) which is used to access the first memory or by a portion (AH) of this address and contains information about which data in the first memory are to be replaced with other data.

Abstract: A control register assembly controls components to be controlled in an electric circuit. The control register assembly includes a control register. The control register is formed by at least one shift register, whose elements are distributed over the electric circuit at mutual intervals, individually or in groups. Such a control register makes it possible to keep short the length of the connecting lines between the control register and the device writing the latter and between the control register and the elements to be controlled thereby.

Abstract: A method described is distinguished by the fact that an external test device brings about the execution, in a program-controlled unit, of a program that initiates, performs or supports the testing of the program-controlled unit. As a result, program-controlled units can be rapidly and reliably tested under all circumstances with minimal outlay.

Abstract: A method and an apparatus for monitoring a process that proceeds automatically to ensure that it is executed properly. The method and the apparatus are distinguished in that one or more error signals signaling errors are generated at the beginning of the monitored process, and in that the generation of the respective error signal is discontinued if the error that is intended to be indicated by the relevant error signal has not occurred.

Abstract: The integrated circuit described is distinguished by the fact that flip-flops which are contained in it and which are not connected in series in normal operation of the integrated circuit can be connected in series at the instigation of the integrated circuit, and/or that flip-flops which are contained in it can be interconnected to form one or more rings. This makes it possible to reduce the outlay for carrying out the burn-in procedure.

Abstract: A driver circuit includes a driver and a control device that controls the driver. The control device modifies the power of the driver based on the waveform of the signal (DAT_OUT) to be driven by the driver and/or based on the waveform of the signal output by the driver. Such a driver circuit makes it possible to reduce the energy consumption of the driver and/or the interference caused by the driver to a minimum.

Abstract: An configuration and a method are described for providing data for characterization of various units on a bus system. The configuration and method are distinguished by the fact that some of the data which characterize a unit are stored in memory elements having a variable content, and in that the rest of the data which characterize the unit are defined by hardware. In consequence, the complexity for providing the data which characterize a unit can be reduced to a minimum.

Abstract: A method for testing an electronic circuit is described, in which the actual state of circuit components which have previously been activated on a test basis after an initial initialization is compared with a setpoint state. Of the circuit components to be tested, essentially only those circuit components are operated simultaneously which, under the given circumstances, can be expected to interact in the context.
