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.

Method for running a computer program on a computer system

In a method for monitoring the functional capacity of an engine controller having a plurality of execution units, a comparison operating mode is provided, in which a torque monitoring program is executed on a plurality of execution units of the system, and signals outputted during the execution of the monitoring program by the execution units are compared with one another in order to recognize an error.

A method and a device for controlling a computer system having at least two execution units, switchover operations being carried out between at least two operating modes, and a first operating mode corresponding to a comparison mode and a second operating mode corresponding to a performance mode. At least one set of runtime objects is defined; at least one identifier is assigned to each runtime object of the defined set; and the identifier assigns at least the two operating modes to the runtime object.

Method and device for controlling a computer system

A method for comparing data in a computer system having at least two execution units, the comparison of the data taking place in a comparison unit and each execution unit processing input data and generating output data, wherein one execution unit specifies to the comparison unit that the next piece of output data is to be compared to a piece of output data of the at least second execution unit, and thereupon a comparison of the at least two output data takes place.

A method and device for performing switchover operations in a computer system having at least two execution units are provided, in which switchover units are included which are configured in such a way that they switch over between at least two operating modes, a first operating mode corresponding to a compare mode, and a second operating mode corresponding to a performance mode. An interrupt controller is provided and, furthermore, at least three memory areas are provided, and the access to the memory areas is implemented in such a way that one first memory area is assigned to at least one first execution unit, and one second memory area is assigned to the at least one second execution unit, and at least one third memory area is assignable to the at least two execution units.

Method and device for performing switchover operations in a computer system having at least two execution units

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.
