Architecture

QuantumSTEP consists of four major levels.
  1. Applications level
    the myApps suite: PIM, Mail, Web Browser, Navigation etc.
  2. Runtime level
    the myPDA runtime environment: X11R6 server, System user interface, Window manager
  3. Library level
    the mySTEP GUI libraries: Foundation, AppKit, AddressBook, SimpleWebKit etc.
  4. Kernel level
    using a standard Linux core as in the Sharp Zaurus-Edition

Applications level

All applications have been rewritten from scratch to optimize the window size and layout of graphical user interface elements to the small, vertical screen of a handheld device.

Runtime level

Here, only the mySystemUIServer (manageing the system menu and loading Menu Extras) has been written from scratch.

Library level

We provide precompiled shared libraries that can be used by all the applications. By using shared libraries, the memory space is kept manageable.

Many of the libraries are open source and we have just compiled them to run on the ARM processor. For others, we have modified the LGPL licenced source code (e.g. mySTEP) and for this, we provide the source as part of the SDK.

Kernel level

Here we use the Linux 2.4.18 standard kernel from Sharp.
