Abstract

Apparatus suitable for detecting a fault in a processor comprises a monitor which receives input and output signals from the processor and generates a hash index key which is used to access entries in a hash table. The entries may include actions such as setting a timer so that the response of an output to a change of state of an input may be confirmed as valid within a specified time interval.
