A method for monitoring a fuel supply system in an internal combustion engine includes the steps of: recording a first pressure value in the fuel supply system in a region of the fuel supply system associated with a pre-filter and upstream of a low pressure pump; recording a second pressure value in the fuel supply system downstream of the low pressure pump in a region of the fuel supply system associated with a primary filter; monitoring the first pressure value and the second pressure value for an error state of the fuel supply system; and recognizing the error state only if the error state is plausible on a basis of both the first pressure value and the second pressure value.

A frequency hopping method for a radio device in which the signal to be transmitted is modulated onto an HF carrier and at least two of the following signal properties are varied in a pseudo-random manner during the transmission after one or more frequency hops: bandwidth, modulation type, and transmission duration of a frequency hop.

Errors which may be detected by an error detection unit may occur during execution of a computer program which runs on a computer system and includes at least one run-time object. In order to handle a detected error particularly flexibly and to keep the computer system available as much as possible, an error handling routine is selected from a pre-selectable set of error handling routines as a function of an identifier assigned to the run-time object and the selected error handling routine is executed.

In a process for receiving a broadband electromagnetic signal, the receiving spectrum is divided into n partial spectrums (n&#x3e;1), which are subjected to parallel further processing in n channels. The resulting n partial signals are then demodulated into the base band, digitized by n equal-type analog-to-digital converters, and spectrally transformed by a fast Fourier Transform. Interfering edge effects at the transition to the respectively adjacent channel are compensated by amplitude and phase correction of the n partial signals for compensating. Finally, the partial spectrums of the n partial signals are integrated to form a total spectrum in the frequency domain.

A method is provided for verifying plotting results when multiple signals of the same frequency have been detected from different directions. Signal characteristics of the signals detected from different directions are compared so that, on the basis of the signal comparison, a decision may be made as to whether a reflection from the same transmitter is occurring, or different transmitters are involved.

A method for running a computer program on computing hardware, in particular on a microprocessor. The computer program includes multiple program objects designed as tasks, for example. Transient and permanent errors are detected during the running of the computer program on the computing hardware. To be able to handle these transient errors constructively when they occur in a computer system in such a way that the functionality and function reliability of the computer system are restored within the shortest possible error tolerance time, at least one program object that has already been sent for execution is set into a defined state on detection of an error and is restarted from this state. The program object is a runtime object of the computer program, for example, also known as a task. One or more tasks that are still being executed or have already been executed on occurrence of an error are restarted and run again.

A method for error detection in a cache memory for storing data, the access to the data stored in the cache memory taking place by addresses assigned to them, wherein for the addresses assigned to the stored data, at least one first test signature made up of at least one first signature bit is generated and also stored in the cache memory.

A method for running a computer program on computing hardware, in particular on a microprocessor, is described, the computer program including multiple program objects and errors being detected in the method while running the computer program on the computing hardware, the program objects being subdivided into at least two classes and program objects of the first class being repeated when an error is detected and, when an error is detected in one program object of the first class, which has already been sent for execution, this program object of the first class being restarted instead of a program object of the second class.

A method for executing a computer program on computing hardware, e.g., on a microprocessor, is provided, the computer program including multiple program objects and errors being detected in the method while running the computer program on the computing hardware. The program objects are subdivided into at least two classes, and multiple program objects are executed during one run, program objects of the first class being repeated when an error is detected and, when an error is detected in one program object of the first class, which has already been sent for execution, this program object of the first class is restarted instead of a program object of the second class after the other program objects of the first class of a run.

A method for executing a computer program on computing hardware, e.g., on a microprocessor, is provided, the computer program including multiple program objects and errors being detected in this method while the computer program is running on the computing hardware. When an error is detected, at least one program object, which has already been sent for execution, is transferred into a defined state and is restarted from there, and subsequent additional program objects are shifted.

A system and method for comparing binary data words are provided, which method includes splitting a first and a second data word (A, B) to be compared to one another into at least two subwords, one having high-order bits (hA, hB) and the other having low-order bits (nA, nB), and separately comparing each pair of the corresponding two subwords (hA, hB; nA, nB) in a separate comparing device. The intermediate comparison results of the comparing devices are gated in a logic device, e.g., an AND gate, to yield an overall result as a function of a control signal which is applied to a correction device, which is connected between at least one of the comparing devices and the logic device.
