摘要： When a NEW SECONDARY CODE EXECUTION START POINT signal is generated in a target processor during a test procedure after the return from an interrupt service routine (i.e., an original secondary code sequence), a sync marker is generated in a program counter trace stream. The sync marker includes a plurality of packets, the packets identifying that the sync marker is has been generated as a result of the NEW SECONDARY CODE EXECUTION START POINT signal. The new secondary program code start point sync marker identifies the absolute program counter address at the time of the generation of the NEW SECONDARY CODE EXECUTION START POINT signal and relates the NEW SECONDARY CODE EXECUTION START POINT signal sync marker to a timing trace stream.

摘要： Data streams are generated for tracing target processor activity. When multiple streams are on, they are written at different times into their individual FIFO. It is possible that for a specific stream, the length and fields of the data that should be exported vary. This invention is a scheme to send out only the relevant fields.

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： While PC trace is o, 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跟踪为o时，跟踪处于预测或一般事件分析模式时，跟踪硬件会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 preventing trace data first-in-first-out buffer overflow in a pipelined data processor stops new instructions when a trace data first-in-first-out buffer is in danger of overflowing. The method also stalls a predetermined number of pipeline stages in the pipeline ahead of the first pipeline stage. The trace data first-in-first-out buffer is emptied while the pipeline is stalled. On restart, the stalled pipeline stages are restarted ahead of re-enabling new instructions. Asynchronous trigger events received during the stall may be buffered and unrolled in order or merely stored and applied simultaneously on restart.

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： 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.
