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： 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.
摘要翻译：在跟踪期间，定时流具有活动和停止信息，PC流具有所有不连续信息，并且数据流具有所有数据日志信息。使用称为同步点的标记来同步各种流。同步点提供唯一的标识符字段和跟随它的数据的上下文。在数据损坏之后，同步点被插入到数据流中。该同步点的ID可以重复先前的同步点ID。

摘要： When an INTERRUPT SERVICE ROUTINE (SECONDARY) 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 INTERRUPT SERVICE ROUTINE CODE FLUSH signal. The interrupt service routine code flush sync marker identifies the absolute program counter address at the time of the generation of the INTERRUPT SERVICE ROUTINE CODE FLUSH signal and relates the INTERRUPT SERVICE ROUTINE CODE FLUSH signal sync marker to a timing trace stream. The INTERRUPT SERVICE ROUTINE CODE FLUSH signal is generated at the transition between the interrupt service routine (secondary) code instructions being removed from the pipeline flattener and the program (primary) code instructions being removed from the pipeline flattener.

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.
