
전원 꺼짐: 이 상태에서는 CPU가 꺼지고 RAM에 전원을 공급하
지 않는다. (모든 플랫폼 장치가 꺼져 있는 상태.)
켜짐: 표준 실행 모드. CPU가 실행되어 스레드를 예약하고,
RAM과 모든 플랫폼 장치에 전원을 공급한다.
유휴 상태: 이 상태에서는 실행되는 스레드가 없고 CPU는 일시
중단 모드에서 인터럽트 예외만 관리한다. RAM에는 전원이 공
급되어 모든 값이 유지하지만 그 외 모든 장치가 켜져 있다.
일시 중단: 이 상태에서는 실행되는 스레드가 없고 CPU는 일시
중단 모드이며 타이머 인터럽트가 중단된다. RAM에는 전원이
공급되어 모든 값이 유지하지만 그 외 모든 장치가 켜져 있다.
위험 전원 꺼짐: 이 상태에서는 CPU가 일시 중단되며, RAM은
자동 새로 고침 상태로 에너지 소비가 가장 적다. 모든 플랫폼
장치가 꺼져 있다.

The OEM Adaptation Layer





Layer between the Kernel and the hardware
Set of functions related to system startup,
interrupt handling, power management, profiling,
time, 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
Windows CE.NET
29
The Kernel Module

Portable across supported processors


NK.EXE, COREDLL.DLL


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


NK.EXE contains Kernel code and Coredll.dll is the operating
system core DLL module
Saving system resources


Kernel is portable as most of the operating system is written
in C
Loads virtual memory pages into physical memory when
needed
Multiple execute in place regions

Allows applications to execute code directly from read-only
memory
Windows CE.NET
30
Device Driver System

Device driver


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



Links an operating system and a device
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 separated the implementation into two layers
Windows CE.NET
31
The GWES Modules

Graphics, Windowing, and Event Subsystem




Graphics output: display and printer
User input: keyboard, stylus, and mouse
Window management: message routing
Graphic Device Interface (GDI)



Is the drawing subsystem of GWES
Control how text and graphics are displayed
Uses a device context to store drawing attributes for a
specified device
Windows CE.NET
32
The Filesys Module

The Filesys Module

Implements the object store






File systems
Registry
Property Database
Substitutes for a hard drive on an embedded drive
Resides in ROM, RAM, or both
Can have a maximum size of 256 MB
Windows CE.NET
33
The Filesys Module (con’t)

Storage manager


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


Is responsible for all external storage items, including all the
file systems and block drivers
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
Windows CE.NET
34
The Filesys Module (con’t)

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
Windows CE.NET
35
Real Time Operating System







Bounded interrupt response latency
Timer precision configurable (1millisecond
default)
System timer tick independent of thread quantum
Nested interrupt support
Priority inheritance
Protected virtual memory
Synchronization objects
Windows CE.NET
36
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
