Discussion of handheld operating systems design.

You have just been given an assignment to develop an operating system for a new hand-held device your company is producing. You evaluate competing products such as the Palm OS, Linux OS, Windows CE and other developed products. While you can see advantages to each OS, you believe you can improve on existing features of the OS.

In a detailed paper, describe what your OS will do, how you will design it and what features will be present. Do not generalize, make this a very specific with diagrams and other supporting materials. There is no programming required.

Introduction

When designing an operating system, the architect must consider not only how the operating system will function internally, but how it will interface with other devices and operating systems and how it will interact with the human user.

Chris Smith has laid out the following categories for OS design consideration on his web site: http://cdsmith.twu.net/professional/osdesign.html:

1. Architecture
2. Booting
3. Devices
4. Processes
5. Memory
6. Filesystems
7. Networks
8. Security
9. User Interface
10. Fault Tolerance
11. Real Time
12. Distributed Systems

Not all of the details of each are fleshed out on his site, but this list does provide an outline to follow.

Characteristics

In my opinion, the following are key characteristics that should be inherent in any modern mobile operating system.
Stable
Operating systems need to be stable. An OS that is continually rebooting or causing applications to fail will be a failure itself. Many factors contribute to OS stability - code ...

Solution Summary

When designing an operating system, the architect must consider not only how the operating system will function internally, but how it will interface with other devices and operating systems and how it will interact with the human user.
