Abstract: A data processing apparatus is provided comprising first processing circuitry. Interrupt generating circuitry generates an outgoing interrupt in response to the first processing circuitry becoming unresponsive. Interrupt receiving circuitry receives an incoming interrupt, which indicates that second processing circuitry has become unresponsive, and in response to receiving the incoming interrupt, causes the data processing apparatus to access data managed by the second processing circuitry.
