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 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.

摘要： A system and method time orders events that occur in various portions of the system (10) where different time domains (12, 22, 32) exist. Timestamping circuitry (e.g. 40) is provided in each of a plurality of functional circuits or modules (14, 24, 34). The timestamping circuitry provides a message that indicates a point in time when a predetermined event occurs. An interface module (70) is coupled to each of the plurality of functional circuits (14, 24, 34). The interface module (70) provides control information to the plurality of functional circuits (14, 24, 34) to indicate at least one operating condition that triggers the predetermined event, and to optionally specify a message format. The interface module (70) provides a timestamping message from one, several or all time domains at a common interface port (90).

摘要： A data processing system and method generates debug messages by permitting an external debug tool to have real-time trace functionality. A data processor executes a plurality of data processing instructions and uses a memory for information storage. Debug circuitry generates debug messages including address translation trace messages. A memory management unit has address translation logic for implementing address translation to translate addresses between virtual and physical forms. The debug circuitry includes message generation circuitry that is coupled to the memory management unit for receiving notice when one or more address translation mappings are modified. The message generation circuitry generates an address translation trace message in response to a detection of a modification of an address translation mapping occurs and provides the address translation trace message external to the debug circuitry.

摘要： An approach is provided in which an endianness violation detection sub-system detects endianness violations between hardware units. The endianness violation detection sub-system tracks memory operations performed by multiple hardware units via debug channels and generates lookup table entries that are stored in a lookup table. When the endianness violation detection sub-system detects endianness relevant load attributes of a load operation that are different than corresponding endianness relevant store attributes of a store operation, the endianness violation detection sub-system generates an endianness violation. In one embodiment, the endianness violation detection sub-system identifies an endianness violation when the endianness violation detection sub-system detects a difference in the byte ordering type between a hardware unit performing a store operation and a hardware unit performing a load operation.
