Windows CE .NET
Architecture The Windows CE .NET operating system from Microsoft provides a
portable, scalable, real-time operating system for embedded devices.
The modular design of Windows CE .NET allows the platform builder
to include only those features required for the specific product
application. However, the Windows CE .NET operating system is still
a subset of the other Microsoft operating systems, and it runs Win32
applications.
Windows CE .NET Benefits
There are three major differences between the Windows CE .NET
operating system and other Microsoft Windows operating systems.
The Windows CE .NET operating system:
•
has a small memory footprint requirement.
•
runs on a wide variety of processor architectures.
•
has a real-time scheduler.
The small memory footprint allows the Windows CE .NET operating
system to operate in small solid-state memory devices (8 MB typical).
In contrast, computers that run Windows operating systems require
hundreds of megabytes of storage space.
The PanelView Plus CE terminal has an x86-based processor to
maximize the consistency between Windows 2000/XP and Windows
CE .NET applications.
