EMBEDDED SYSTEMS
What are embedded systems? ... How this automation is possible, lies in the fact that these products
have a smart microprocessor embedded in them. The intelligence of smart devices
resides in embedded systems. An embedded system is the combination of Hardware,
Software & additional devices designed to perform a particular task.
Classification of Embedded Systems:
1. Autonomous
Embedded systems used for process control in manufacturing units and
automobiles fall under this category. ... Networked
Embedded systems can connected to the intranet or the Internet. This
enhances the utility of the embedded systems manifold. These systems
monitor the temperature, pressure and humidity in a plant and send the
data over the network to a centralized system for online monitoring. ... Mobile
These mobile systems are to store databases in their memory, perform
both real time and non-real-time tasks and handle multimedia
applications. ...
Applications of the embedded system
In spite of the above uses that we have seen embedded systems can be applied in the
following fields.
Aerospace & Defense Applications
Telecommunications
Consumer & Internet Applications
Digital Imaging
Automotive
Broadcast & Entertainment
Embedded System design includes
I. ...
Memory
An embedded system needs both RAM and some variant of ROM. In most
embedded systems, which do not have a disk drive or other storage medium, the entire
program must be in ROM. ... This is
actually a debugger, which is used to debug the embedded software that has been
created. ...
Examples of real time operating systems are VxWorks, pSoS,
WindowsCE, LynxOS
III. ...
Programming Languages
The low-level languages and high languages that can be used to write
programs for an embedded system are
Assembly Language
C
C++
Java and some more
Some Real time Examples
Sony Corp has developed a robotic dog called Aibo.
