Method and apparatus for simulated error injection for processor deconfiguration design verification
Patent number: 6728668Abstract: A method and apparatus for simulated error injection for processor deconfiguration design verification is provided. A simulated error condition request is received from a user through software, such as the operating system executing in the multiprocessor data processing system. In response to the requested simulated error condition, an error condition is injected into a processor of the multiprocessor data processing system via instruction execution. In response to the detection of the error condition and execution of error-path code, a processor is deconfigured.

Patent number: 6718253Abstract: A method for forming an actuating variable to be output periodically by a control unit in output periods for controlling an apparatus, in particular the ignition or fuel injection of internal combustion engines, includes reading output signals of at least two sensors into the control unit and ascertaining individual components of the actuating variable based on the output signals. The sensor output signals are read-in and the individual components are determined periodically at intervals of one read-in period or one determination period being equal to or a multiple of the output period of the actuating variable. The read-in period of a sensor output signal is dependent on a speed of variation of the sensor output signal, and in particular it increases as the maximum speed of variation of the sensor output signal decreases. The determination period of each individual component is dependent on the read-in periods of the sensor output signals involved in each individual component.Type: GrantFiled: April 29, 1994Date of Patent: April 6, 2004Assignee: Siemens AktiengesellschaftInventors: Helmut Wellnhofer, Reinhold Dirnberger
