What’s an Operating System?


Provides environment for executing programs

Process abstraction for multitasking/concurrency
Scheduling
Hardware abstraction layer (device drivers)
Filesystems
Communication

We will focus on concurrent, real-time issues

Real Time Operating Systems for Networked Embedded Systems


Fire Alarm System

Problem
Hundreds of sensors, each fitted with Low Range Wireless
Sensor information to be logged in a server & appropriate action initiated
Possible Solution
Collaborative Action
Routing
Dynamic – Sensors/controllers may go down
Auto Configurable – No/easy human intervention.
Less Collision/Link Clogging
Less no of intermediate nodes
Fast Response Time
Secure

Open Real-time Robotics Control - PC Hardware, Windows/VxWorks Operating Systems and Communication
Abstract
In the modern robotics systems the users must combine hardware, operating
systems and network. Robot controller is a real-time operating system with multiple
tasks and processors, the hardest real-time requirements are in path control, there
coordinated movements of multible axes and other tasks must be controlled. The
robotics society is going to increase PC’s as part of the control platforms. Same time
modularised, dist ....etc

ABSTRACT
Within the last ten years real-time systems research has been transformed from a
niche industry into a mainstream enterprise with clients in a wide variety of industries
and academic disciplines. It will continue to grow in importance and affect an increasing
number of industries as many of the reasons for the rise of its prominence will persist for
the foreseeable future.
What is RTOS?
Real Time Computing and Real Time Operating Systems( RTOS ) is an
emerging discipline in software engineering. This is an embedded technology w ....etc

Real-time systems play a considerable role in our society, and they cover a spectrum from the very simple to the very complex. Examples of current real-time systems include the control of domestic appliances like washing machines and televisions, the control of automobile engines, telecommunication switching systems, military command and control systems, industrial process control, flight control systems, and space shuttle and aircraft avionics.

All of these involve gathering data from the environment, processing of gathered data ....etc
