20080201618 | Method for Running a Computer Program on a Computer System - 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. | 08-21-2008 |

The error handling routines are designed in each case to refresh different subsets of the set of variables. | 08-13-2009 |
20090217090 | Method, operating system and computing hardware for running a computer program - 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. | 08-27-2009 |
20090217107 | Method and Device for Data Processing - A method and device for data processing having at least three identical or similar execution units, wherein at least one comparator exists and at least two execution units are grouped such that the output signals of the at least two execution units are connected with the at least one comparator and compared. | 08-27-2009 |
20090254773 | Method, operating system and computing hardware for running a computer program - 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. | 10-08-2009 |
