Proposal for “ Android” Performance and Power Analysis Platform on VisualSim

1. Proposal for“Android” Performance and Power Analysis Platform on VisualSim To: Mirabilis Design Inc. April 28th, 2009 TOPS Systems Corp. Yukoh Matsumoto Takeshi Ohkawa Michiya Hagimoto

2. 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 Our Goal

3. 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 onAndroid Market Many chip venders quickly stated porting and demonstrating Android ARM, TI, Qualcomm, NEC, Freescale, Marvell, Renesas Related news..

13. 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. What to show to impress customers

14. Let’s make great success!
