    students the opportunity to work on real world
    projects, with hardware, software and technical
    support provided by Microsoft
  • Target Audience Undergraduate Computer
    Engineering/ CS students worldwide.
  • Especially relevant for Senior Design/ Senior
    Project courses

How does it work
Windows Embedded Challenge
Application
Students build apps using .Visual Studio .NET (C
VB) or Embedded Visual C (C or C)
Windows CE.NET
Customizable by students with Platform Builder,
the Windows CE IDE (also provided to teams)
Board Support package
Provided to participating teams through ICOP
Hardware
  • Contest among undergraduate students
  • Build a computer based system based on the theme
    Going beyond the boundaries
  • Collaboration with CSIDC - IEEE
  • James Madison University Champions, 2004

5
Microsoft Technical Support
Windows Embedded Challenge
  • Helpp_at_microsoft.com
  • Manned by over 25 Windows CE developers
  • Get answers to questions about Windows CE
    Software how to configure, build, debug and
    deploy OS image
  • This was one of the most valuable resources last
    year for students
  • Will not help with writing code
  • Frequent Online chats
  • Other resources (books, etc) available on request

OS Versus Platform Why distinguish between the
two?
  • Because Windows desktop development blurs
    differences between them, causing confusion
    w.r.t. the embedded space.
  • To draw attention at some differences between
    Windows CE and other Windows OS.
  • To set the stage for talking about Tools.
  • To highlight some opportunities and design
    choices coming at us like an avalanche.

8
Avalanche Wide Range of Devices
Voice-over IP Devices
Gateways
Thin Clients
Set-Top Boxes
Digital Audio Receivers and Players
Mobile Handhelds
Medical Devices
IndustrialAutomation
Smart Displays
9
Avalanche Devices in Automobiles
10
Avalanche 2500 Partners
  • Over 2,500 Windows Embedded Partners worldwide
  • Exponential growth in China, Taiwan, India
  • Gold partners in all major regions
  • Industry experts
  • Demonstrating value across product line

11
Operation Systems Are
  • Webster Dictionary
  • The Master Control Program that starts when a
    Computer boots
  • Abstracts the hardware for applications
  • Offers standard APIs to access Hardware
  • Is not useful without hardware
  • You cannot just develop for an OS
  • Examples
  • Windows XP, Windows CE, Linux,

12
Platforms Are
  • A specified set of OS technologies defined as
    components for a specific set of hardware
  • In the embedded space these are usually defined
    by the OEM
  • Applications are developed targeting the
    platform
  • The Platform SDK defines the platform
  • Microsoft platforms
  • Windows 3.1, Windows 98, Windows XP, Pocket PC,
    Pocket PC 2002, SmartPhone

13
Windows XP versus Windows CE
  • Windows XP as a platform
  • Uniform platform with significant app
    compatibility
  • Restricted hardware architecture
  • Readily available, inexpensive
  • Windows CE as OS
  • A collection of components that can be assembled
    into a wide variety of platforms
  • Much more flexibility about the hardware since it
    supports 4 processor architectures
  • X86
  • SH4
  • ARM
  • MIPS

14
Design Choices
  • Build your own platform
  • Greater flexibility regarding choice of
    components to include
  • Platform designer supplies kernel and drivers
  • More work
  • Develop towards an existing platform
  • App level environment already exists
  • You probably cant change it
  • You can get stuck if you need a component thats
    not available

15
CE Technology ComponentsKernel, Power Manager,
File System
  • Hard real-time preemptive multitasking kernel
  • Interprocess communication (IPC), sync objects
  • Memory mapped files, message queues, fibers
  • Virtual memory with hardware access protection
  • Installable ISRs, Multimedia timers, DMA APIs
  • more flexibility for drivers apps
  • Kernel hooks for profiling and debugging
  • Flexible Power Manager with power profile states
  • Layered Storage Manager Architecture
  • File system Filters
  • E.G. for adding FS Encryption
  • Sample file system drivers in PB
  • FATFS, CDFS/UDFS, BinFS (Flash file system)

16
CE Technology ComponentsNetworking
Communications
  • Self tuning TCP/IP stack, incl. IPv6 Support
  • NDIS 5.1 driver architecture RNDIS supported
  • Winsock 2 WinINet
  • Wireless networking
  • Bluetooth, including qualified profiles
  • 802.11, Auto configuration 802.1x security
  • Services LDAP, DCOM, SOAP, MSMQ, UPnP,

  • Portable Music Device
  • Robot
  • Embedded Devices
  • Soft PLC
  • HMI Panel
  • HVAC Controller
  • Sewing Machine
  • Traffic Light

  • Cash Register

21
Embedded Devices
  • No power consumption optimization
  • Might not have a display
  • Application durability is most important
  • Software gets pre-installed
  • By OEM, Machine Builder, SP
  • Optimize for application footprint
  • Mobile Devices
  • Optimization for power management
  • 99 have displays
  • User Experience and ease of use is essential
  • Footprint still important
  • Larger application may not install with default
    memory settings

22
Platform Builder
  • Creates platforms with Windows CE
  • Assembles OS components into a device image
  • Mainly for OEM but also for driver development
  • Exports the platform SDK for embedded Visual
    Tools
  • Windows CE.NET PB exports to eVC 4.0
  • Emulator facilitates software development
    independent of hardware
  • Platform wizards walk you through component
    selection for common device types
  • Components can be added by dragging and dropping
    from the catalog
  • Dependency checking automatically brings in other
    needed components
  • New components can be written from scratch
