EMBEDDED SYSTEMS .doc (Paper Presentation)

ABSTRACT:

Embedded system is the most advanced computing system in the world today, which has rapidly gained acceptance and market world wide. With embedded chips fast reaching the power of main stream CPUs, we prepare for the inevitable invasion of the do-it-all devices that will be part of our every day life. It increased reuse of pre-designed components e.g., DSP chips, microprocessors, microcontrollers. The focus of attention shifted from pure desktop machine to handheld and embedded devices such as palmtops and home entertainment systems. The present paper discusses functions, components, features, characteristics and applications of embedded systems. It also discusses about one of the main application PDA, its features and uses.

INTRODUCTION:

With the increasing demand and decreasing cost of computing resources, triggered a move from timesharing to the personal computer, one can expect current technology trends and application requirements to trigger a move from the personal computer to the networked appliance, the sensor net, and the highly mobile user interface device. The users of tomorrow can interact with many computers. Some of these will continue to support general purpose computing, some will be dedicated to providing human-level interfaces, and some will be embedded in the environment in which we see smart devices, sensors, actuators and so on.

This is the strange world of embedded computer system where specially customized computer chips chug away beneath the hoods of a host of mundane items of mass consumption-from washing machine, fridge's, cars and computers, camera's and wristwatches -even the garment one may soon where.

The field of embedded systems has been steadily growing over the past couple of years. Embedded systems involve the miniaturization of electronics so that it can fit into compact devices. It also deals with the software required to drive the associated hardware. This year, embedded systems received a lot of attention, due to the rise of portable devices like handhelds, PDAs, Internet set-top boxes, etc. Moreover, wireless devices and technologies like Bluetooth have also seen a lot of development.
