== Principle and Advanced of Embedded Systems 1-Introduction. 2-Meaning Embedded System(EMS). 3-Types of Embedded System. 4-Type of design embedded system. 5-Application Embedded System.

Introduction
After revolution electronic manufacture and invention Integrated circuit which are consist of many complex called chip , versus development computer languages such as  assembly, C,C++,java, ISP, languages. As well as competition many of the integrated circuit makers are production smaller chip, fast more, and power little consumption. These are factors assistance of build technology called embedded System in a world.

Meaning Embedded System(EMS)
Embedded System (EMS): First : Refer to the many of unites connect with a logic Method are working together contained in chip (Integrated circuit )and the chip acceptable programming with a programming  language to constructed as Embedded system(EMS). Second :refer to the Integrated circuit builds inside many of unites connect with a logic method are working together, this integrated circuit acceptable software programming to performing special operation which design for it.

types of Embedded system
there two types of the (EMS): 1-Embedded system software. There are three kinds of the (EMS)software: a-Firmware is a permanently program which must found to required operation. b-Application performs the main function of the system and simple system may have only one application running. c- Operating System supervises and supports execution of multiple applications and contains of the real-time variety, for system requiring deterministic response times. 2-Embeded System Hardware. It contains of the : a-Processor: is the heart and brain or the main player. b-Memory : program Memory is contains applications, firmware &operating system. c- Interface Circuits ,I/O ports as windows to the outside world. d-Interrupt Controller manages processor-I/O dialogs.

Type of Design Embedded System
-Simple Embedded Systems Like Microcontroller have -single 4-16bit, simple hardware and software ,may even be battery operated, assembly or c language is used for developing these stem and need to limit power dissipation when system is running continuously. -Complex Embedded systems 32-bit processor cores, large memory, enough to accommodate on operating system, may contain multiple processors, Battery /AC operated, Multiple language may be used to program C,C++,java, forth python etc and requires complex development tools.

Application Embedded Systems
There are many applications are used Embedded system  such as communication ,vehicles ,industry control, economic, aerospace, and medical device etc. -Rocket & satellite control -Telephone switches -Air Traffic Control -Personal Digital Assistants (PDAs) -MP3 players -Mobile phones -Video game consoles -Digital cameras -DVD players -GPS Receivers -Printers
