Weert ca, , /0 Port, , , , , , Microprocessor is heart of Computer system., , Micro Controller is a heart of embedded syst, , , , , , It is just a processor. Memory and I/O components, have to be connected externally, , Micro controller has external processor along with, internal memory and i/O components, , , , Since memory and I/O has to be connected externally,, the circuit becomes large., , Since memory and I/O are present internally, the, circuit is small., , , , Cannot be used in compact systems and hence, inefficient, , Can be used in compact systems and hence it is an, efficient technique, , , , Cost of the entire system increases, , Cost of the entire system is low, , , , Due to external components, the entire power, consumption is high. Hence it is not suitable to used, with devices running on stored power like batteries., , , , Since external components are low, total power, consumption is less and can be used with devices, running on stored power like batteries., , , , Most of the microprocessors do not have power saving, features., , Most of the micro controllers have power saving modes, like idle mode and power saving mode. This helps to, reduce power consumption even further., , , , Since memory and I/O components are all external,, each instruction will need external operation, hence it, is relatively slower., , Since components are internal, most of the operations, are internal instruction, hence speed is fast., , , , Microprocessor have less number of registers, hence, more operations are memory based., , Micro controller have more number of registers, hence, the programs are easier to write., , , , Microprocessors are based on von Neumann, model/architecture where program and data are stored, in same memory module, , , , Micro controllers are based on Harvard architecture, where program memory and Data memory are separate, , , , , , Mainly used in personal computers, , Used mainly in washing machine, MP3 players
