  1. Windows Phone OS CS342302 Operating System 9960103陳建寧 9960106陳立昂

  2. Outline • User Interface Overview • Windows Phone History • Programming languages and IDEs supported • OS Structure • App Lifecycle and Process Isolation • Multiprogramming and Multitasking • Scheduling employed • Threading supported • Future view ( Windows Phone 8.1 )

  3. User Interface Overview • Lockscreen • Metro (Modren)UI • App list

  4. Windows Phone History Windows Mobile 201010/11 Windows Phone 7 2011 9/27 Windows Phone 7.5 Windows Phone 8 Windows Phone 7.8 20126/21

  5. Programming languages and IDEs supported

  6. Programming languages and IDEs supported • IDE supported • Visual studio • Blend for Visual Studio

  7. App lifecycle • Not running • Running • Dormant • Tombstoned

  8. Process Isolation

  9. Multiprogramming CPU foreground background App App App App

  10. Multitasking • Fast Application Switching • Fast Application Resume • Idle detection

  11. Scheduling employed • Background agent (subset of an App) • Periodic, Resource Intensive, Dual Purpose task • Does not support all API

  12. Threading supported • Each thread maintains • exception handlers • a scheduling priority • a set of structures the system uses to save the thread context until it is scheduled • Preemptive (time slice) • Provide thread pool API

  13. Future view • Windows Phone 8.1

  14. Future view • Windows Phone 8.1 • More API availabe • User-define UI

  15. Conclusion • UI – modern (live tile) UI • Programming language - C/C++/C#/Visual Basic/XAML • Kernel – same as windows 8 • Multiprogramming – background / foreground • Multitasking – Fast App Switch/Resume • Scheduling – Background Agent • Thread – preemptive(time slice)

  16. Feedback • 開發環境統一，方便於開發者debug或移植 • OSUI布局較簡單，layout設計不複雜 • 提供簡約風格，自成一格 • 許多API未開放給開發者，第三方程式發展受限 • Multitasking的應用對於一般使用者較不友善

  17. Reference • Windows Phone Dev Center http://dev.windowsphone.com/en-us/ • MSDN-Microsoft Developer Network http://msdn.microsoft.com/en-us • MVA-Microsoft Virtual Academy http://www.microsoftvirtualacademy.com/ • Wikipedia http://en.wikipedia.org/wiki/Main_Page • My Lumia 920
