EMBEDDED SYSTEMS .doc -- RTOS (Paper Presentation)

DEFINATION:-

A real-time operating system (RTOS) is an operating system that guarantees a certain capability within a specified time constraint.

In general, real-time operating systems are said to require:

• multitasking
• Process threads that can be prioritized
• A sufficient number of interrupt levels

Real-time operating systems are often required in small embedded operating systems that are packaged as part of micro devices. Some kernels can be considered to meet the requirements of a real-time operating system. However, since other components, such as device drivers, are also usually needed for a particular solution, a real-time operating system is usually large

THE FUNDAMENTALS:

To most people, embedded systems are not recognizable as computers. Instead, they are hidden inside everyday objects that surround us and help us in our lives. Embedded systems typically do not interface with the outside world through familiar personal computer interface devices such as a mouse, keyboard and graphic user interface. Instead, they interface with the outside world through unusual interfaces such as sensors, actuators. Real-time and embedded systems operate in constrained environments in which computer memory and processing power are limited. They often need to provide their services within strict time deadlines to their users and to the surrounding world. It is these memory, speed and timing constraints that dictate the use of
