What is Embedded System?
Embedded System is a system which perform some limited task or a system which are designed to perform a specific application. If we talk about Camera, Refrigerator are Embedded system. Because Camera is designed only to take picture and record videos. But if we talk about a Computer, it can not be terms as a Embedded system because many application can be perform in computer by simply installing Application Program on it. Usually embedded systems does not have more user interface, but a General Purpose System are having more user interface.
Reset Circuitry: To restart or reboot the system.
ADC/DAC: Analog to digital conversion is to process the signal or data in digital circuitry. And Digital to analog conversion to make output understandable to humans (Physical signal).
Difference Between Embedded System and General Purpose System.
Embedded means something that is attached to another thing. An embedded system can be thought of as a computer hardware having software embedded in it.
The application areas and the products in the embedded domain are countless.
1. Consumer Electronics: Camcorders, Cameras.
2. Household appliances: Washing machine, Refrigerator.
3.Automotive industry: Anti-lock breaking system(ABS), engine control.
4. Home automation & security systems: Air conditioners, sprinklers, fire alarms.
5. Telecom: Cellular phones, telephone switches.
6. Computer peripherals: Printers, scanners.
7. Computer networking systems: Network routers and switches.
8. Healthcare: EEG, ECG machines.
9. Banking & Retail: Automatic teller machines, point of sales.
10. Card Readers: Barcode, smart card readers.

The basic block diagram for any Embedded System is shown below.
Core: It is the controlling and main part of the system. A perfect micro controller, microprocessor, FPGA, CPLD, COTS or DSP processors can be used as core in Embedded system as per respective application.
Communication Interface: If Embedded system is having requirement of communication with anather devices or system any specific communication protocol can be use. Selection of communication protocol is based on required range and speed of data transfer.Reset Circuitry: To restart or reboot the system.
ADC/DAC: Analog to digital conversion is to process the signal or data in digital circuitry. And Digital to analog conversion to make output understandable to humans (Physical signal).
