developers can compile controller software in the Windows XP environment,
and then transfer the code to Embedded XP for immediate use. System
developers do not need to learn any new tools to use XP Embedded. Their
experience on Windows XP can be directly transferred to XP Embedded, thus
lowering software development costs. Another advantage is that the cost of
licensing Embedded XP is much less than that of Windows XP.
Currently ADLINK provides the standard XP Embedded OS image for GEME
(customers must pre-purchase an XP Embedded license from ADLINK), The
standard XP Embedded OS image provided by ADLINK is about 200 MB for
the English language version, and 400 MB for Chinese language version. For
this OS configuration, a CF card is the best storage device for GEME. The
major functions inside the standard XP Embedded OS image are as follows
• XP Embedded OS Kernel
• Drivers for GEME H/W and peripheral cards
• TCP/IP Networking
• TCP/IP with file sharing and client for Microsoft network
• Internet Explorer
• File Manager
• Language Support
The standard XP Embedded OS image can meet most application needs. If the
customer has special functional requirements for XP Embedded, please
contact ADLINK’s field application engineers (FAE) for more detail about this
OEM service

Windows CE
Windows CE 4.2 incorporates a fresh new look. Because Windows CE is
designed with embedded systems in mind, it requires much less storage space
than does XP Embedded. Windows CE typically needs 64MB of storage space
and it is possible to reduce this amount if necessary. An important feature of
Windows CE supports real-time functionality. Microsoft has tried to keep API
naming conventions and the development process consistent between
Windows CE and Windows XP. But because Windows CE has an embedded
architecture (as compared with Windows XP’s desktop system concept), the
software development process will have significant differences. Newcomers to
the embedded world must keep this in mind. Another factor to consider when
deciding whether to use Windows CE is that licensing costs are much less than
XP Embedded, thanks to Microsoft’s recent promotions.
