EMBEDDED System???....1)An embedded system is a special-purpose computer systemdesigned to perform one or a fewdedicated functions.2) Physically, embedded systems rangefrom portable devices such as digitalwatches and MP4 player to largestationary installations like traffic lights,factory controllers, or the systemscontrolling nuclear power plants.
Embedded system:- An intro. An embedded system is a computer systemdesigned for specific control functions within alarger system .• Embedded systems contain processing coresthat are typically Microcontrollers .
Microprocessor1) A microprocessor incorporates the functions of acomputers central processing unit (CPU) on asingle integrated circuit.2) It is a multipurpose, programmable device thataccepts digital data as input, processes it accordingto instructions stored in its memory, and providesresults as output
MICROCONTROLLER ??? …• microcontroller (also microcontroller unit, MCU or µC) is a small computer on a single integrate circuit consisting of a relatively simple CPU .
Microprocessor v/s MicrocontrollerMicroprocessor: Microcontroller:• Memory is not there. • It has owes Memory.• Microprocessor only • Microcontroller canprocess the i/o data. also process the data.• Microprocessor has more • A Microcontroller isgeneralized functions. more specific to its task.• Brain of any computing • Microcontroller ismachine. complete Computing machine.
Atmel AVRThe AVR is a Modified Harvard architecture 8-bitRISC single chip microcontroller (µC) which wasdeveloped by Atmel in 1996. The AVR was one ofthe first microcontroller families to use on-chipflash memory for program storage, as opposed toOne-Time Programmable ROM, EPROM, or EEPROMused by other microcontrollers at the time.
