摘要： A method of generating timestamped trace messages includes generating a trace message in response to an event at an instruction pipeline of a data processing device. If timestamping is enabled, timestamps are only included in the trace message only if a programmable condition is detected. For example, a timestamp can be included in the trace message if the amount of space used to store messages at a trace message buffer exceeds a watermark value. The condition that results in a timestamped trace message is programmable, and can be selected via a debug interface. Because timestamps are only included in trace messages when the programmable condition is satisfied, some trace messages will not include a timestamp, thereby reducing the amount of buffer space needed to store the trace messages.

摘要： A method provides a data acquisition message of a data processing system to an external port thereof. Configuration information is written to a configuration register. It is determined if the configuration information identifies a data acquisition operation. If the data acquisition operation has been identified, data corresponding to the configuration information is written to a data register. The data in the data register and the configuration information in the configuration register are formatted into the data acquisition message. The data acquisition message is sent to the external port of the data processing system.

摘要： In a data processing system, a marked bit is used to identify a data access instruction throughout the pipeline to indicate that the instruction meets user-specified criteria (e.g., a meets a data address range of interest). Based on the marked bit, an in-order program correlation message is generated which indicates when the data access instruction occurs relative to the instruction stream. The marked bit is also used to generate an in-order data trace message. As a result, the trace streams including only data access instructions meeting user-specified criteria may be post-processed and correlated precisely.

摘要： In one or more embodiments, a data processing system can include at least one core capable of executing instructions of an instruction set architecture and a trace unit coupled to the at least one core. A call to a subroutine can be detected, and in response, a program trace correlation (PTC) message can be generated and sent to a trace port. Data associated with an execution of the subroutine and/or performance of the data processing system can be sampled and sent to the trace port. A return from the subroutine can be detected, and in response, a trace message can be generated and sent to the trace port. The PTC message and the trace message can be correlated, and the correlation of the PTC message and the trace message can be used to determine a boundary for the subroutine and/or the sampled data associated with the execution of the subroutine.
