Proposal for

“Android” Performance and Power Analysis Platform on VisualSim

TOPS Systems All rights reserved. Confidential April 28th, 2009

Our Goal World-Wide Press Release : Success Story

We developed Performance and Power analysis Platform for “Android” on VisualSim very quickly “Quick development” of SW&HW platform on VisualSim Enable hardware and software exploration for Performance and Power optimization for “Android” based HW/SW development

TOPS Systems All rights reserved. Confidential April 28th, 2009

Motivation

Many cell phone makers facing “Power Wall”

Needs of Virtual Platform for Performance and Power Optimization VisualSim could provide platform for optimization

Enable Performance and Power Profiling and Tuning with running real Java Applications on Android

– Application : Android application written in Java– SW Platform : Android SDK http://code.google.com/android/download.html– HW Platform : ARM9/11 Library, Memory Libraries, etc. on VisualSim

Huge expectations on Android Market Many chip venders quickly stated porting and demonstrating Android

ARM, TI, Qualcomm, NEC, Freescale, Marvell, Renesas

What to show to impress customers Android HW/SW running on VisualSim platform

We can run any Android applications We can see what’s happening on SW and HW platform

Where is the bottle neck

Visualize the Performance and the Power “Performance Meter”

Performance Profile : CPU, SDRAM, Flash, WiFi “Power Meter”

Power profile : CPU, SDRAM, Flash, WiFi, LCD, Touch Screen

Optimize Application Software for Performance and/or Power Need power control, smart

Optimize Hardware architecture for Performance and/or Power need Multi-Core, Low-Power memory, Back Light Control, etc.
