摘要:
A data processing apparatus is provided, configured to carry out data processing operations on behalf of a main data processing apparatus, comprising a coprocessor core configured to perform the data processing operations and a reset controller configured to cause the coprocessor core to reset. The coprocessor core performs its data processing in dependence on current configuration data stored therein, the current configuration data being associated with a current processing session. The reset controller is configured to receive pending configuration data from the main data processing apparatus, the pending configuration data associated with a pending processing session, and to store the pending configuration data in a configuration data queue. The reset controller is configured, when the coprocessor core resets, to transfer the pending configuration data from the configuration data queue to be stored in the coprocessor core, replacing the current configuration data.
