Intel® Platform Analysis Technology

Capabilities for software and hardware debugging, performance tuning, and more.

Overview

Intel® Platform Analysis Technology (Intel® PAT) delivers functionality to enable monitoring, diagnosis, and optimization of platforms based on Intel architecture. Intel PAT can also be used for data center management, cloud resource management, and security monitoring.

Features

Platform Monitoring

Provide performance, power, and resource utilization data.

Tracing

Deliver deep insight into system and software implementation.

Debugging

Enable run control, JTAG connectivity, and Direct Connect Interface (DCI) for closed chassis access.

Tools

Browse available tools built on Intel PAT.

Platform Monitoring

Using a consistent interface, software and tools can efficiently access data from the Performance Monitoring Unit (PMU) of Intel microprocessors.
This includes data such as instructions retired, branch instructions retired, page walk types, cycle durations, and more.

Tracing Capabilities

Intel® Trace Hub (Intel® TH)
Debug and optimize code by exposing accurate and detailed traces to quickly identify where problems are occurring. Use the consistent framework to aggregate and output a system's trace data to system memory and industry-standard trace ports.

 

Intel® Processor Trace (Intel® PT)
Log information about a program’s performance without significantly slowing the system. Obtain precise software behavior information including timing and instruction pointer information.

 

Architectural Event Trace (AET)
Deliver a trace of events that occur while running software, which could include modification of the processor state, reaction of the processor to external events, or interaction between the processor and external devices. Contact your Intel representative to learn how you can get access to AET technology.

 

Intel® Processor Trace Decoder Library
The library comes with a set of sample tools built on top of it and a test system built on top of the sample tools. The samples demonstrate how to use the library and may serve as a starting point for integrating the library into your tool.
