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.
摘要翻译：提供跟踪数据系统，其中生成刷新请求信号并将其传递到跟踪数据源，以触发它们输出它们正在存储的任何缓冲的跟踪数据，该数据是在发送刷新请求之前生成的。当跟踪数据从这些跟踪数据源中刷新时，它们会通过生成一个完整的完成信号来发出信号。跟踪数据的刷新可以有利地在掉电操作之前和使用跟踪总线桥处执行。

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： 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.

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 data processing apparatus is provided which is configured to select 2M selected identifiers within a possible range of up to 2N identifiers, where M≦N. The data processing apparatus comprises a selection storage unit configured to store N+1 identifier selection bits, wherein a position of a marker bit in the N+1 identifier selection bits determines M, and an identifier selection unit configured to determine the 2M selected identifiers. The 2M selected identifiers are defined by a base identifier and 2M−1 identifiers incrementally following that base identifier. N−M bits of the N+1 identifier selection bits form N−M most significant bits of the base identifier, and M trailing zeroes form the M least significant bits of the base identifier.
