Concurrent system-level error detection techniques using a watchdog processor are surveyed. A watchdog processor is a small and simple coprocessor that detects errors by monitoring the behavior of a system. Like replication, it does not depend on any fault model for error detection. However, it requires less hardware than replication. It is shown that a large number of errors can be detected by
