Streamline Performance Analyzer

Overview

The growing need for high-performance and energy-efficient

consumer products has changed the shape of embedded systems

and consequently the requirements of software developers.

The ARM® Development Studio 5 (DS-5™) toolchain, through its

ARM Streamline™ Performance Analyzer component, delivers a

simple and intuitive way to analyze and optimize complex Linux and

Android™ based platforms.

ARM Mali GPU Support

The Streamline Performance Analyzer gives you visibility of

performance data across the Cortex processor and Mali GPU, so

that bottlenecks on either side can be easily spotted. It enables

developers to easily balance the overall computing load to make

efficient usage of system resources.

Key Features and Benefits

• Locate ARM application processor hotspots at process, thread

and source code level

• Analyze the efficiency of parallel code on multicore platforms

• Find and optimize bottlenecks across Cortex processors and

ARM Mali™ GPUs

• Zero-in on the top functions causing performance-penalty events

(e.g. cache misses, and branch mispredictions)

• Improve energy efficiency with actual power measurement data

• Long term data capture over TCP/IP interface

• Simultaneous analysis of multiple applications.

Timeline Analysis

Collected data is displayed on a timeline that enables viewing of

software and system-level activity over time. This helps to identify

performance issues that arise from the interaction of the software

with the hardware blocks on the SoC.

Key features:

• Multicore-aware performance charts, process and thread activity,

and instrumented annotations synchronized over time

• Over 40 core-dependant PMU counters, over 300 Mali GPU

counters, plus several OS performance metrics available for

monitoring

• Time-based filtering on software profile analysis

• Thread activity mapping per core on SMP systems.

The Architecture of the Digital World®

CPU, GPU, and OS-level performance graphs are time-correlated with process/thread

activity per core and software profiling.

Flexible Architecture

Easily customize the Streamline Performance Analyzer to collect

and visualize SoC specific data.This flexibility can be used to

monitor statistics from peripherals, fabric, and other processors

interconnected with the Cortex processor.
