摘要： A method and system of indexing into trace data based on entries in a log buffer. At least some of the illustrative embodiments are methods comprising executing a traced program on a target device. The traced program writes entries to a log buffer within the target device, and the traced program also contemporaneously writes an index value for each entry to a register. The index value written to the register becomes part of trace data regarding the traced program and correlates each entry to a respective portion of the trace data. Using the information one may either or both: display on a display device a portion of the trace data (the portion selected based on selecting an entry from the log buffer); or display on the display a portion of the log buffer (the portion selected based on selecting an entry from the trace data).

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： 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： 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。

摘要： A saturating count counts received event signals up to a first predetermined number. An overflow counter counts overflows up to a second predetermined number. The counter indicates overflow when the overflow count is non-zero and saturates and stops counting at a maximum count when the overflow count reaches the second predetermined number. The counter can be read via a register read operation. The sum of the sum of the first predetermined number of bits and the second predetermined number of bits being an integral multiple of 8 bits.

摘要： This invention provides trace address compression by comparing respective bytes of a current trace address with a stored prior trace address. Only the least significant bytes of the current trace address that do not match the stored prior trace address or are less significant than any section of the current trace address that does not match the stored prior trace address are transmitted. This sometimes reduces the amount of data that needs to be transmitted. The prior trace address may be updated with the current trace address if there is a complete mismatch.
摘要翻译：本发明通过将当前跟踪地址的各个字节与存储的先前跟踪地址进行比较来提供跟踪地址压缩。只有当前跟踪地址中与存储的先前跟踪地址不匹配或者比当前跟踪地址中与存储的先前跟踪地址不匹配的任何部分不太重要的最低有效字节被传送。这有时会减少需要传输的数据量。如果存在完全不匹配，则可以使用当前跟踪地址更新先前的跟踪地址。

摘要： When a RESET signal is generated in a target processor during a test procedure, a reset sync marker is generated in a program counter trace stream. The reset sync marker includes a plurality of packets, the packets identifying that the reset sync marker is the result of a RESET signal. The packets identify the program counter address at the time of the generation of the RESET signal and relate the reset sync marker to a timing trace stream. When the RESET signal is removed, a second (reset-off) sync marker is generated identifying the removal of the RESET signal, identifying the program counter address, and relating the second sync marker to the timing trance stream.
