What is an embedded system?
An embedded system is a special purpose system, in which the
computer is encapsulated by the device it controls. Unlike a
general purpose system an embedded system will only perform some
particular tasks. These are actually systems which are developed
for performing some predefined tasks. Embedded systems may vary
from small hand held devices like PDAs to large devices like
Embedded systems are generally control systems which are a part of another device and they can handle the entire operation of that device. They are generally electronic chips with CPU, memory,I/o ports and are programmable.
It is because the basic definition of embedded system is that it involves hardware and software for a single application. The device that is using an operating system may be an embedded system. But the operating system itself is not an embedded system It is because that it is only a software but not the combination of hardware and software.
An embedded system can include an Operating System to perform support functions for the application software and hardware. Because of the restrictive nature of an embedded system, its operating system will be compact and more efficient and will exclude many of the capabilities necessary in a general operating system. No. It is because the basic definition of embedded system is that it involves hardware and software for a single application. The device that is using…
An embedded system is a system dedicated for a particular real time application,with a factory pre programmed microcontroller or microprocessor in it.The processor (and/or)controller used in embedded system are referred to as embedded processor or embedded controller (which may be ordinary or special purpose micro controller or microprocessor).
Embedded system is a combination of software and hardware. To complete some tasks, we need hardware and to control the hardware, we need some software. This is the basic principle of an embedded system. Every equipment which has a single application and uses hardware and software is an embedded system. The importance of embedded system can be found in robotics, signal and image processing, communication etc.
# A specialized computer system that is part of a larger system or machine. Typically, an embedded system is housed on a single microprocessor boardprograms stored in ROM. Virtually all appliances that have a digital interface -- watches, microwaves, VCRs, cars -- utilize embedded systems. Some embedded systems include an operating system, but many are so specialized that the entire logic can be implemented as a single program. # Embedded System is: specified purpose controller…
