6.1 Introduction

The TREK510 platform is one embedded system with Windows® Embedded CE 5.0. The
Windows® Embedded CE 5.0 is a compact OS that occupies less storage space or system
resources compared with other operating systems such as Windows
®
 XP. By its modular
nature, it is possible to choose those functions that are useful for specific application. Not
only reducing the system resources required,  but also reduces start‐up time. In the field of
embeddedapplications, this is an appealing featurebecause theimpact ofdowntime would
beminimized.
Furthermore, the small storage space it needs makes OS on solid-state disk possible, which implies higher robustness to harsh environments.
