Embedded System
In this world of knowledge everything around us is run by Computing Systems. The technical Brilliance and Developments in different fields has led to a drastic change in our lives especially in the communications field. Due to various changes in technologies many systems have come up with breathtaking developments. One amongst them is the Embedded Systems. It is the evolution or further development of computing system. Its applications provide tremendous opportunities for creative use of computer technology. Almost every new system introduced in the market is an example of Embedded System.
An embedded system is a combination of computer circuitry and software that is built into a product for purposes such as control, monitoring and communication without human intervention. Embedded systems are at the core of every modern electronic product, ranging from toys to medical equipment to aircraft control systems.
In contrast to general-purpose computers, embedded systems perform a narrow range of pre-defined tasks. Thus, they usually do not have any of the typical computer peripheral devices such as a keyboard, display monitor, serial connections, mass storage (e.g., hard disk drives), etc. or any kind of user interface software, unless required by the product in which they are used in. This can make it possible to greatly reduce the complexity, size and cost and increase the robustness of embedded systems as compared with general purpose systems.
SECTION V:
The introduction of high-end technologies, digital signal processing and VLSI has changed the face of the world. The man has tended to become safer, secure and at same time reducing the overhead of labour using these technologies.
In embedded technology, the embedded Programming is burnt into the AT89C51 micro controller. The project includes 7 SEGMENT LED DISPLAY, which will display the corresponding number given as an input from keypad and soft ware code, which is burned in to ROM of 8051 micro controller consists of various subroutines for keypad interface, 7 segment led interface.
Main advantage of this project:
It mainly useful in any Organization (Public) &private sectors.
Low cost
Simple maintenance
Effective manner and duration of time period also less
