11. The OEM Adaptation Layer Layer between the Kernel and the hardware Set of functions related to system startup, interrupt handling, power management, profiling, timer, and clock Included in BSPs for supported SDBs Coded by OEMs to adapt windows CE to their own custom platforms Linked with code provided by Microsoft to build the Kernel

12. The Kernel Module Portable across supported processors Kernel is portable as most of the operating system is written in C NK.EXE, COREDLL.DLL NK.EXE contains Kernel code and Coredll.dll is the operating system core DLL module Saving system resources CE loader is designed to save system resources by loading application pages as and when needed and by keeping only one physical copy of a DLL Demand paging Loads virtual memory pages into physical memory when needed Multiple execute in place regions Allows applications to execute code directly from read-only memory

13. Device Driver System Device driver Links an operating system and a device Built-in Drivers vs. Installable Drivers Built-in drivers are installed by the platform manufacturer Installable drivers are third-party peripheral devices that end users can connect to a Windows CE-based platform Native Drivers vs. Stream Drivers All of the device drivers managed by GWES are native device drivers Device manager loads stream interface drivers when the system boots, if those drivers are listed in the registry Monolithic Drivers vs. Layered Drivers Monolithic drivers implement interface directly in terms of actions on the device they control Layered drivers separate the implementation into two layers

14. The GWES Module Graphics, Windowing, and Event Subsystem Graphic output: display and printer User input: keyboard, stylus, and mouse Window management: message routing Graphic Device Interface (GDI) Is the drawing subsystem of GWES Controls how text and graphics are displayed Uses a device context to store drawing attributes for a specified device

16. The Filesys Module (continued) Storage manager Is responsible for all external storage items, including all the file systems and block drivers Installable file systems Can provide access to a floppy diskette, a hard drive, a flash file system on a PC Card, or to other external storage devices File-shadowing mechanism Allows a file to be stored both in RAM and ROM. Differences from other Windows file systems No letters assigned to file systems No concept of current directory No support for overlapped I/O All files stored in RAM are automatically compressed

17. The Filesys Module (continued) Registry Provides a common repository for system settings, application data, and user preferences Resides in RAM, if not present in RAM, the registry can be reloaded from persistent storage or rebuilt from ROM Registry functions specific to Windows CE Property Database Provides a lightweight database management system Accessible using a new set of Win32 API functions specific to Windows CE Data stored in a flat model Accessible to ActiveX Data Objects for Windows CE (ADOCE) Supports multiple volumes on installable file systems

18. Real Time Operating System Bounded interrupt response latency Timer precision configurable (1 millisecond default) System timer tick independent of thread quantum Nested interrupt support Priority inheritance Protected virtual memory Synchronization objects

19. Power Management Features Power management features respond to system calls for turning the system off or for idling Device level power states, DO-D4 D0 – Full on: Full power with full functionality D1 – Low On: Slightly reduced functionality, lower power and/or performance D2 – Standby: Partial power with automatic wake D3 – Sleep: Partial power with device initiated wake D4 – Off: Power off The only device power state that all devices must support is D0, full on

41. Internationalization (continued) Common practice for developing international software: Use a few target locales for initial development and testing Resource Localization: Strict or Non-strict Translation Tips Avoid using vague words, colloquialisms, jargon, acronyms, and abbreviations Use good grammar Avoid dynamic concatenation of different strings Avoid hard-coding file names in a binary file Avoid including text in images and icons International Conventions Locales might have different conventions for expressing information Locales might have different keyboard conventions
