Hard and soft realtime operating system

[redflower]

Hello,
How are you?
Excuse me, do you have any information about real time operating system?
:sad::-(Because I want to write a report about it and it will include these following points:

* An Introduction to real‐time operating systems in general
* Explain how and why they are different from general purpose operating systems such as Windows
* The areas where they are used.
* Discuss how HARD / SOFT real time operating system is one such OS.
* Describe how HARD / SOFT real time operating system does kernel organization, memory management and process management.

THANK YOU

Here are some good references (they're not particularly recent), if you're close to a library:
Burns; Wellings - Real Time Systems and Programming Languages
Bennett - Real Time Computer Control: An introduction
Castelli - EOS: IEEE Micro Oct 1985
Labrosse - uC/OS book
Cooling - Software Design for Real-time Systems
Also, it's worth reading some of the books people have written about space flight, or aircraft possibly - I can't think of the names of any off-hand.
