摘要： During a trace the timing stream has the active and stall information, PC stream has all the discontinuity information, and the data stream has all the data log information. The various 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. After data corruption a sync point is inserted into the data stream. The ID of this sync point may repeat a previous sync point ID.

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.
摘要翻译：追踪数据处理器活动的方法，从检测到跟踪流损坏中恢复。如果检测到损坏后的第一个跟踪数据不是程序计数器同步点，则跟踪以最后发送的程序计数器同步点的程序计数器地址的偏移格式发送当前程序计数器地址的指示，然后发送跟踪事件偏移格式的数据。如果检测到损坏后的第一个跟踪数据是程序计数器同步点，则跟踪将以事件偏移格式发送跟踪数据。

摘要： A method of tracing data processor activity includes trace data markers indicating initiation and termination of at least one trace function at a specified program counter address and emulation pause related markers indicating initiation and termination of an emulation halt state at a specified program counter. Each emulation pause related marker includes a conflict bit indicating the presence or absence of a simultaneous trace data marker having a different program counter address.

摘要： A method of tracing a data processor upon reset of the data processor. A data processor reset signal resets the data processor, part of trace collection hardware and does not reset remaining parts of trace collection hardware. The data processor reset signal may be not owned, owned by an application program or owned by a debugger. The partial not reset of the trace collection hardware occurs only upon a data processor reset signal owned by the debugger. A trace logic reset signal resets both the data processor and the trace collection hardware when not owned. This trace logic reset signal resets the data processor only when owned by the debugger and resets the trace collection hardware when owned by an application program.

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.
摘要翻译：生成跟踪数据流以跟踪目标处理器活动。使用称为同步点的标记来同步各种跟踪数据流。同步点提供唯一的标识符字段和跟随它的数据的上下文。所有跟踪数据流可以产生具有该唯一标识符的同步点。这些唯一标识符允许在多个跟踪数据流之间进行同步。当多个跟踪数据流打开时，数据输入速率可能高于数据输出速率。如果在这种情况下同步丢失，则必须有一个方案来重新同步流。本发明是用于该需要的再同步的技术。

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： 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.
摘要翻译：软件流水线循环跟踪方法涉及在软件流水线循环（SPLOOP）的开始时禁止跟踪数据的输出。如果SPLOOP被跳过，则在输出跟踪数据包中跳过，并且如果SPLOOP未被跳过，则SPLOOP在输出跟踪数据包中的epilog状态的周期处被指示。迭代计数指示SPLOOP信息和SPLOOP内的位置被维护。如果SPLOOP处于活动状态，则会输出与同步点一致的周期性SPLOOP标记（PerSP）。

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。
