  1. Anatomy of mobile systems Lin Zhong ELEC424, Fall 2010

  2. Outline • Physical • Integrated circuit • Software • Cost • Power profile • Administration

  3. Physical profile: Case study • HP Jornada 928 • Released in 2002 • TI OMAP 710 133MHz • 64MB RAM • CompactFlash I • 221 grams • QVGA refective TFT display • GSM/GPRS • Windows Pocket PC 2002

  4. Component stack-up (17mm) Portable Electronics Product Design & Development, Bert Haskell, 2004

  5. Weight profile Which parts are most likely to become lighter?

  6. Physical trend • Lighter but not necessarily smaller • More integrated • Jornada 928 has about 600 discrete components • System-in-a-package (SiP) • Digital RF • Single-chip cell phone Source: ICCAD’05, Bogdan Staszewski, TI

  7. Integrated circuit: Jornada 928 • Simplified block diagram (Bert Haskell)

  8. Software profile Applications Libraries (graphics, e.g. OpenGL, user interfaces, e.g. Qt) Managed runtime (Java virtual machine, .NET framework) Operating system Device drivers (System interface to peripheral devices) Firmware (BIOS, fixed software in microcontrollers)

  9. Cost profile Source: PEPDD, Bert Haskell Total cost: $170.5

  10. Cost profile (Contd.) $199 with AT&T plan >$700 from ebay without plan

  11. Cost profile (PC) • Dell Inspiron 1420 basic system: ~$650 (08/08) • Including Windows Vista Home: ~$200 (retail) • Office 2007-Student:~$100 • Professional version :~$500 • Security software: ~$100 (three years) Software is really expensive!!!

  12. iPhone 3GS teardown

  13. iPhone 3GS teardown (Contd.)

  14. iPhone 3GS teardown (Contd.)

  15. Power for audio delivery Power profile: Pocket PC iPAQ 4350, 2004

  16. Power profile: Smartphone Audiovox 5600, 2004

  17. Power profile: Interactive tasks A computer spends most of its energy in idle periods due to the human-computer speed mismatch Display power significant User delays Power trace for Calculator on a Sharp Zaurus 5500 99% time and 95% energy spent waiting during interaction

  18. Power profile: Make a call Ringing Voicemail

  19. Power profile: Browse web Back lightings change Downloading (cnn.com)

  20. Power profile: Play video Speaker on Speaker off 30-minute of streaming video will exhaust the battery

  21. Industrial profile Services Verizon, Sprint, AT&T etc. Applications Nokia Apple RIM (Blackberry) Microsoft Operating system Samsung, LG, HTC, Moto,… Palm System integration/manufacture IC TI, ARM, MIPS (Digital), Qualcom • Broadcom, Marvel (RF, Analog)
