摘要： Trace data streams are generated for tracing target processor activity. Various trace data streams are synchronized using markers called sync points. The sync points provide a unique identifier field and a context to the data that will follow it. All trace data streams may generate a sync point with this unique identifier. These unique identifiers allow synchronization between multiple trace data streams. When multiple trace data streams are on, it is possible that the data input rate may be higher than the data output rate. If synchronization is lost in such a case, there must be a scheme to resynchronize the streams. This invention is a technique for this needed resynchronization.

摘要： A method of trace collection in a data processor begins trace data collection even if a trace trigger is received during an interval when a central processing unit is stalled. Trace data collection is deferred if a trace trigger is received during an interval of an invalid instruction boundary until a valid instruction boundary.
摘要翻译：即使在中央处理单元停滞的间隔期间接收到跟踪触发，数据处理器中的跟踪收集方法也开始跟踪数据采集。如果在无效指令边界的间隔期间接收到跟踪触发，直到有效指令边界，则跟踪数据收集被延迟。

摘要： When events are traced, the timing stream is used to associate events with instructions and indicate pipeline advances precluding the recording of stall cycles. Additional information is needed in the trace stream to identify an overlay whose execution of code is in a system where overlays or a memory management unit are used. In the case of PC trace, additional information is added when the memory system contents is changed. Information describing the configuration change is inserted into the export streams by placing this information in a message buffer. As long as a message word is available for output, it becomes the next export word as the output of message words is continuous.

摘要： A method and system of identifying overlays used by a program. The overlays may be executable overlays (e.g., overlay programs and dynamically linked library programs), or the overlays may be data sets. Depending on the number of overlays and/or the type of information used to identify the overlays, an indication of the identity of the overlays may be written to a register (whose contents are inserted into the trace data stream), or the indication may comprise an entry in a log buffer and an index value written to the register (again whose contents are inserted into the trace data stream, and where the index value identifies the entry in the log buffer).

摘要： A software pipelined loop tracing method involves inhibiting an output of trace data at a start of a software pipelined loop (SPLOOP). A skip in an output trace packet is indicated if the SPLOOP is skipped, and the SPLOOP is indicated at a cycle of an epilog state in the output trace packet if the SPLOOP is not skipped. An iteration count indication SPLOOP information and a position within a SPLOOP, is maintained. A periodic SPLOOP marker (PerSP) coinciding with a sync point is output if the SPLOOP is active.

摘要： While PC trace is on, and the trace is in predication or general event profiling mode, trace hardware captures events in each cycle. Trace hardware inserts this information into data logs, and does a right shift to compact the data. The trace window will eventually close, either because tracing has been turned off, or because a periodic sync point is generated to reset the window. In either of these two cases, the data log may be incomplete, fully packed, or just overflow into the next packet. An index is generated pointing to the last valid location in the data log in order to save transmission bandwidth.
摘要翻译：当PC跟踪打开时，跟踪处于预测或一般事件分析模式，跟踪硬件捕获每个周期中的事件。跟踪硬件将此信息插入到数据日志中，并进行正确的转换以压缩数据。跟踪窗口将最终关闭，因为跟踪已被关闭，或者由于生成周期性同步点来重置窗口。在这两种情况下，数据记录可能不完整，完全打包，或者只是溢出到下一个数据包中。生成指向数据日志中最后一个有效位置的索引，以便节省传输带宽。

摘要： A method of tracing data processor activity with recover from detection of trace stream corruption. If the first trace data following detection of corruption is not a program counter sync point, then the trace transmits an indication of the current program counter address in an offset format from the program counter address of a last transmitted program counter sync point and then transmits trace data in event offset format. If the first trace data following detection of corruption is a program counter sync point, then the trace transmits trace data in event offset format.
