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 having one or more trace data sources is provided in which the trace data sources operate to generate respective streams of trace data. At least one of said trace data sources comprises 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. The synchronization marker identifies a synchronization position in the trace data stream. A controller is coupled to the synchronization marker generator, and operates to initiate 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 with respect to trace data flow. 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, thereby reducing the likelihood of the volume of trace data resulting in an overflow condition in the downstream circuitry.

摘要： A trace data system is provided in which flush request signals are generated and passed to trace data sources to trigger them to output any buffered trace data they are storing which was generated prior to the flush request being signalled. When the trace data has been flushed from these trace data sources, they signal this by generating a flush complete signal. The flushing of trace data may advantageously be performed prior to a power-down operation and using a trace bus bridge.

摘要： A count value generator includes an input for receiving a synchronizing count value, a counter configured to increment at a local frequency, the local frequency being faster than the synchronizing frequency, and an interpolator for determining a frequency ratio between the local frequency and the synchronizing frequency and for determining an increment value for the counter dependent on a relative amount of a maximum value of the counter with respect to the frequency ratio is disclosed. The counter generates a count value including a predetermined number of bits representing integer values and output as the lower order bits of the output count value and additional lower order bits that represent fractional portions of the integer values. The counter includes output circuitry for outputting the synchronizing count value and the predetermined number of bits representing integer values generated by the counter as the lower order bits of the count value.

摘要： An integrated circuit is provided with multiple data processing components associated with respective sources which generate trace data streams. A reference timestamp generator is provided and the trace data streams are annotated such that they are output off-chip together with reference timestamp data. Outputting the reference timestamp data together with the trace data streams enables temporal correlation between points in different trace data streams by trace analysis tools.

摘要： An integrated circuit 2 is provided with multiple sources 12, 14, 16, 18 of trace data streams that are input via respective dedicated trace buses 20, 24 to a trace data stream combiner 22, 26.

摘要： A trace data formatter 30 assembles trace data frames 50. These trace data frames 50 include bytes which may either serve to carry a trace data source identifier ID or trace data. A system being traced has multiple trace data sources 12, 14, 16, 18 and when the trace data source which is generating the current trace data stream changes then a trace data source identifier ID is inserted within the trace data stream.
