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:
A method and system of profiling streaming channels. At least some of the illustrative embodiments are methods comprising executing a traced program on a target system (the traced operating on a plurality of streaming channels), obtaining values indicative of which of the plurality of streaming channels the traced program has operated on (the obtaining by a host computer coupled to the target system), and displaying on a display device an indication of a proportion of an execution time the processor of the target system dedicated to each of the streaming channels.
摘要:
An information carrier medium containing software that, when executed by a processor, causes the processor to receive information from caches on different cache levels. The caches comprise a plurality of cache line addresses, each cache line address associated with a corresponding name. The software causes the processor to display the information on a graphical user interface (GUI), the GUI cross-referencing each of the cache line addresses with a corresponding name.
摘要:
The present disclosure describes methods and systems for secure debugging and profiling of a computer system. Some illustrative embodiments may include a system including a processor with a first processing stage and a first attribute register associated with the first processing stage, and including a memory system coupled to the processor. An instruction and an attribute value are stored within the memory system, wherein the instruction is loaded into the first processing stage and the attribute value is loaded into the first attribute register. Export of debug and profiling data from the first processing stage is disabled if the attribute value in the first attribute register indicates that the instruction in the first processing stage is a secure instruction, and further indicates that secure emulation is disabled.
