Analyzer Suite A collection of system analysis and visualization tools leveraging multiple technologies

to provide powerful debug and optimization solutions for multi-core application

Bring multiple technologies together to maximize visibility into different levels of the system

PC and CPU Event Trace (hardware instrumentation)

Common Platform (CP) Tracer to count bus events (hardware instrumentation)

Unified Instrumentation (UIA) (software instrumentation)

Simulator Instrumentation

LTTng Instrumentation (software instrumentation)

Data from different technologies and cores correlated to a common timeline for a more complete system solution

Choice of data transports allow adopting to different usage scenarios including remote access

JTAG (run and stop mode)

Ethernet

STM (System Trace Module)

UART

System analysis and visibility using software instrumentation from multiple cores correlated to a global timeline

Unified Instrumentation Architecture (UIA) defines a set of APIs, interfaces and guidelines to collect data in real-time using software

instrumentation

allow instrumented components from different groups to play well together

Analyze system locally or remotely Connect to target via Ethernet, JTAG or UART

Linux target host support Can transport via Ethernet on Linux host

Output logs to Linux Terminal

Live or capture and post-process

Runtime control to enable/disable logging

Easy to use analysis and visualization tooling enable by Data Analysis and Visualization Technology (DVT) Execution Graph

Duration Analysis

Context Aware Profile

Load Analysis

Statistics Analysis


Multicore Data Correlation

4

Correlate multiple streams of data to a global timeline Sync logs injected into data streams

Sync log contains local timestamp and system timestamp

Sync logs fed into a timeserver on host to correlate different data streams

Correlated events can be analyzed graphically on a single timeline Visibility into what activities are happening on what cores and when

Timeserver enable correlation across tools from multiple vendors Timeserver is developed in open source community

Messages

Events

Trace


System Analyzer: Analysis Features

5

Execution Graph to monitor task execution states across system OS task and user start/stop events

Latency/duration Analysis Determine how long operations are taking

Number of occurrences of operation and minimum, maximum, average time taken

Base on start/stop software instrumentation

Function Profiler Function profiler on hardware using software

instrumentation

Context and interrupt aware

Compiler function entry/exit hook can be leveraged to simplify instrumentation


System Analyzer: Analysis Features

6

CPU load analysis Monitor overall CPU loading and task

loading on CPU

Summary analysis of CPU loading

Monitor system resource (such as heap) usage Resource usage logged via software

instrumentation

Data visualized graphically with summary analysis


System Analyzer: Instrumentation Package Unified Instrumentation Architecture (UIA) target package for

instrumentation

Provide target-side APIs, transports, interfaces and guidelines that enable instrumentation that is portable and flexible

Built on RTSC (open source) technology

DSP/BIOS instrumented out-of-the-box

Guidelines on how to instrument other RTOSes

UIA Portability and Flexibility

ISA independent - reusable across wide range of TI single-core and multi-core devices

O/S independent - not tied to specific operating system

Transport independent - no source code change to switch transport

Platform independent - host-side tooling works on both Windows and Linux


Trace Analyzer Analyze and visualize CPU PC and data trace

Statistics & Logic Analyzer Analyze system bus transactions and traffic using CP Tracer

9

Data Captured using STM (System Trace Module) and post process in Logic Analyzer

Two throughput Counters to counts bytes of slave acknowledged accesses

Wait Counter to counts number cycles a master access wait for slave acknowledge

Access Counter to counts the number of unique transactions

Event logging of new request, last read and last write event

Bus bandwidth profile % bus activity utilized by selected master(s)

Bus Bandwidth utilized by selected master(s)

Average Access Size of slave transactions

Bus Utilization

Contention Percentage

Minimum Average Latency

Graphical event timeline viewing of System Trace events and messages

Graphically visualization of statistics/through-

put/bandwidth data


Simulator Profiler Leverage the simulator profiler for situations where

Hardware is not available or

Analysis solution available on hardware does not satisfy the required use case

Function Profiler using simulator PC discontinuity trace

10

Count number of times functions are called

Calculate total inclusive and exclusive cycles spend in function

Inject OS context switch information for context and interrupt awareness

Code Coverage

Determine is source lines are fully, partially and not executed at all

Analyze percentage of function coverage

Also supported on hardware using compiler instrumentation

Data structure Profiler

Analyze how many times data structures are read from or written to

Fully executed == Green

Partially == Yellow

Not executed == Red


Analyzer Suite 1.1 – 2Q’11 Accessibility of CPU Trace and CP Trace data

Leverage ETB to eliminate need for expensive emulator

Drain ETB to system memory to virtually extend ETB buffer size

Transport ETB data via UIA transport to allow for non-JTag support

Bring different technologies together for a more complete solution

Pull LTTng data into Analyzer Suite for inclusion in analysis

Correlate UIA, LTTng, CPU Trace and STM data to a common timeline

Extend multi-core use cases

Multi-core concurrency analysis to determine if cores are well utilized in parallel

Task lock/wait analysis to determine how much time is spent blocked or waiting other tasks or resources

Usability

Add Compare feature to determine changes across multiple runs


Analyzer Suite 1.2 – 3Q’11 Primarily focus will be on simplifying uses cases (especially hardware

instrumentation based use cases)

Introduce the Analysis Suite Dashboard

Single place to access all use cases (hardware and software instrumentation based)

Integrated configuration, control and feedback. This is currently buried in different places such as Trace Control and UBM

Improve user feedback

Summary view for all analysis

Additional use cases in dashboard leveraging hardware instrumentation
