    摘要: A method of tracing program counter activity in a data processor periodically transmits a program counter sync point including the current program counter address. Between sync points the program counter address is indicated by a program counter offset relative to the last program counter sync point. The program counter offset is sent as integral number of sections of a predetermined number of bits. Program counter sync points are transmitted often enough so that the program counter offset requires at most one less section than the program counter address.

    摘要: Navigating trace data. A traced program, or the operating system responsible for the traced program, writes index values to a particular hardware location, which index values become part of the trace data by operation of hardware devices in the target system. A debug-trace program (executed either in an attached host computer or as an embedded debugger) uses the index values to assist the user of the debug-trace program in navigating to particular portions of the trace data based on the index values.

    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: Code will switch to secure code via an exception only. All PC and data trace will be turned off during secure code. This will occur regardless of trace being in standard trace mode or event profiling mode. Timing, if on, will switch to standby mode. On return from the secure code, the switches that were already on will switch back and turn on. The address reported in the end sync point will be the address 0x01. Since this is an illegal address, this information is sufficient to indicate an end sync point was caused in secure code.

    摘要翻译: 代码将仅通过异常切换到安全代码。 所有PC和数据跟踪将在安全代码期间关闭。 无论跟踪在标准跟踪模式还是事件分析模式下,都会发生这种情况。 如果开启,则会切换到待机模式。 从安全代码返回时,已经开启的开关将切换回并打开。 报告在最后同步点的地址将是地址0x01。 由于这是一个非法的地址,所以这个信息足以表明在安全代码中造成结束同步点。
