Název v původním jazyce

Temporal relationship extension of state machine observer

Popis výsledku v původním jazyce

In general, safety applications use operation flow monitoring to detect loss of integrity due to hardware or software faults. Operation flow monitoring may detect bugs in hardware or software in addition to design flaws that cause race conditions or unintended events. If implemented effectively and efficiently, operation flow monitoring, in conjunction with other, higher level, measures, may replace hardware lock-step techniques used to ensure timely detection of hardware faults and to reduce or eliminate unsafe consequences. Operation flow monitoring may use watchdog processing to detect incorrect operation flow. Typical watchdog processing techniques use at most one watchdog per processor core, which may be insufficient to monitor all tasks that need to be monitored. Individual differences in time constraints between different check points may be difficult to observe. In addition, conventional techniques use in-line code monitoring that requires substantial overhead and has difficulties dealing with non-determinism. Furthermore, in-line code monitoring may not yield a substantial improvement with respect to hardware fault detection. Accordingly, improved techniques for monitoring operation flows in a processing system are desired.
