摘要： A trace module generates timestamps while tracing characteristics of a data processing apparatus or processing is performed by the data processing apparatus. When a predetermined event occurs, a timestamp request flag is set to indicate that a timestamp request is pending. Upon generation of a following trace packet, it is determined whether the timestamp request flag indicates that a timestamp request is pending, and if a request is pending then a timestamp is generated corresponding to the following trace packet, and the timestamp request flag is set to indicate that there is no pending timestamp request.

摘要： A data processing apparatus having one or more trace data sources. At least one of said trace data sources includes a trace data generator responsive to activity in monitored circuitry to generate trace data representing said activity. A synchronization marker generator is coupled to the trace data generator and operates to generate a synchronization marker and insert the synchronization marker into the trace data stream. A controller is coupled to the synchronization marker generator to generate and insert a synchronization marker into the trace data stream. The controller controls initiation in dependence on behavior of the data processing apparatus downstream of the trace data generator. In this way, the downstream behavior of the data processing apparatus can be made to influence the rate and timing of insertion of synchronization markers into a trace data stream.

摘要： A data processing apparatus is provided comprising processing circuitry and instruction decoding circuitry. The data processing apparatus is capable of operating at a plurality of different privilege. Processing circuitry of the data processing apparatus imposes on program instructions different access permissions to at least one of a memory and a set of registers at different ones of the different privilege levels. A debug privilege-level switching instruction is provided and decoding circuitry is responsive to this instruction to switch the processing circuitry from a current privilege level to a target privilege level if the processing circuitry is in a debug mode. However, if the processing circuitry is in a non-debug mode the instruction decoding circuitry prevents execution of the privilege-level switching instruction regardless of the current privilege level.

摘要： A method of generating an event log of game events associated with elements in a sporting event. The method includes tracking, within a sequence of video images, image features which correspond to respective elements in the sporting event and selecting, from the tracked image features, a first image feature which corresponds to one of the elements so as to designate that element as a selected element. The method further includes selecting a game event from an event list of possible game events for association with the selected element, and associating the selected game event with the selected element so as to generate the event log.
