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： 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： This invention provides trace address compression by comparing respective bytes of a current trace address with a stored comparison address. Only the least significant bytes of the current trace address that do not match the comparison address or are less significant than any section of the current trace address that does not match the comparison address are transmitted. This sometimes reduces the amount of data that needs to be transmitted. The comparison address is specified by a central processing unit via a memory mapped register write operation.

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： A system and method of tracing a group of processor events in real-time in order to enable a programmer to debug and profile the operation and execution of code on the processor. This may be accomplished by running one or more traces on the same or different groups of processor events in order to gain a full understanding of how code is being executed by the processor.

摘要： When tracing memory events the required bandwidth may be reduced by forming a logical OR of several memory event signals to determine the location of memory events. A second trace run may be made after this, tracing only the limited portions of the application where the first run indicated possible problems.

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： 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： A method of tracing activity of a data processor generates a trace data stream during a normal background mode and a foreground mode while servicing a real time interrupt during an emulation halt. An Interrupt During Suspend bit is set in foreground modes and transmitted in the trace data stream to distinguish the trace data streams between background mode and foreground mode.
