This document discusses embedded systems and compares microprocessors and microcontrollers. It defines an embedded system as a computer system designed to perform one or a few dedicated functions and are controlled by microprocessors and microcontrollers. The document notes that embedded systems are made to perform only a few tasks and cannot be used for other purposes after implementation. It lists characteristics of embedded systems like being single-functioned, tightly constrained by factors like cost and size, real-time, complex algorithms, and user interfaces. The document then explains that microprocessors contain only a CPU chip and require external additions like RAM and ROM to function, while microcontrollers integrate CPU, RAM, ROM and peripherals onto a single chip.

1. EMBEDDED SYSTEM
 DINESH KUMAR
 EC(3RD
YEAR)
 VCTM ALIGARH

2. Content to be discussed
 Introduction
 Microprocessor vs microcontroller
 Buring a program into microcontroller

4. KEY POINTS
 AN EMBEDDED SYSTEM IS A COMPUTER
SYSTEM DESIGNED TO PERFORM ONE
OR A FEW DEDECATED FUNCTION.
 CONTROLLED BY MICROPROCESSOR
AND MICROCONTROLLER
 IT IS MADE TO PERFORM FEW TASK
ONLY.AFTER IMPLEMENTATION YOU
CAN’T USE THEM FOR ANOTHER
PURPOSE.

7. CHARACTERISTICS OF
EMBEDDED SYSTEMS
 Single Functioned
 Tightly Constraint(Manufacturing Cost,
Performance,Size, Power)
 Real Time and Reactive
 Complex Algorithms
 User Interface
 Multi Rate
 Is laptop an embedded system?—This
question will be answered shortly!

9. Microprocessor
 A Silicon chip that
contain a CPU
 It does not have
RAM,ROM&OTHER
PERIPHERAL on
the chip
 a system designer
has to add them
externally to make
them functional

10. MICROPROCESSOR
DIAGRAM

11. MICROCONTROLLER
 It has a cpu in, addition with a
fixed amout of ram,rom and
other peripherals all on a
single chip.
 Other peripherals like
TIMER,ADC,DAC,I/P O/P
PORTS
 It is also called as a mini
computer or computer on
single chip.
