摘要:
A system comprises a circuit configured to execute instructions and output event data corresponding to the execution of the instructions. The system also comprises a monitoring device coupled to the circuit. The monitoring device receives information about said event data. The event data comprises event data selected from a group consisting of memory events and external events.

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.
摘要:
An information carrier medium containing software that, when executed by a processor, causes the processor to receive information from circuit logic that is adapted to collect the information from caches on different cache levels. At least some of the information from the caches is associated with a common address. The processor also provides the information to a user of the software.

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:
Disclosed herein is a system and method for executing a series of instructions on a circuit. An encoder receives event data corresponding to the executed instructions, wherein the encoder groups the event data into one or more groups and outputs the highest priority event for each group.
摘要:
Stall monitoring systems and methods are disclosed. Exemplary stall monitoring systems may include a core, a memory coupled to the core, and a stall circuit coupled to the core. The stall circuit is capable of separately representing at least two distinct stall conditions that occur simultaneously and conveying this information to a user for debugging purposes.

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 applications that use virtual memory. At least some of the illustrative embodiments are methods comprising executing a traced program on a target system (the traced program comprising a plurality of tasks, each task using a different virtual to physical memory mapping), obtaining values indicative of a plurality of states of virtual to physical memory mapping used by a memory management unit associated with a processor of a target system, and displaying an indication of a proportion of an execution time the processor of the target system dedicated to each of a plurality of tasks during the execution time.
摘要:
Profiling operating context. At least some of the illustrative embodiments are a computer-readable medium storing a program that, when executed by a processor, causes the processor to obtain values indicative of a state of an operating context parameter during execution of a traced program on a target processor, and display an indication of a proportion of time during a trace period of the traced program that the target processor operated with the operating context parameter in a particular state.
摘要:
An information carrier medium containing software that, when executed by a processor, causes the processor to receive information from circuit logic that is adapted to collect the information from caches on different cache levels. Each of the caches comprises a plurality of cache lines, and each cache line is associated with a way. The software also causes the processor to reassign the way of a cache line to a different way.
