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.

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： When a PROGRAM CODE FLUSH signal is generated in a target processor during a test procedure, 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 PROGRAM CODE FLUSH signal. The program code flush sync marker identifies the absolute program counter address at the time of the generation of the PROGRAM CODE FLUSH signal and relates the PROGRAM CODE FLUSH signal sync marker to a timing trace stream. The PROGRAM CODE FLUSH signal is generated at the transition between the program (primary) code instructions being removed from the pipeline flattener and the interrupt service routine (secondary) code instructions being removed from the pipeline flattener.

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： A method of tracing activity of a data processor includes collecting and transmitting trace data. An epause marker is embedded in the trace stream upon detection of an emulation halt. This epause marker includes a little offset indicating a number of latency instructions within trace collection hardware since a program counter exception. This permits the utilization emulation device to annulling trace data corresponding to the latency instructions.

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.
