Original Abstract Submitted
An apparatus has bridge circuitry to communicate transport packets between a transport network and data processing circuitry. Some or all of the data processing circuitry operates in a given reset domain other than the reset domain of the transport network. The apparatus also has packet tracking circuitry to monitor the transport packets received at the bridge circuitry and to track whether any required responses have been provided. The reset handling circuitry is responsive to a reset request for the given reset domain to: cause the bridge circuitry to reject new transport packets received for the domain; and when the packet tracking circuitry indicates that all required responses have been provided, accept the reset request for the given reset domain and allow the data processing circuitry to carry out a reset for the data processing circuitry operating in the given reset domain.
