This presentation summarizes a summer training project on embedded systems. It introduces the presenting company, defines embedded systems, and classifies them. It then describes the main components of embedded systems like microprocessors and microcontrollers, providing details on the 8051 microcontroller including its pin diagram and descriptions. Examples are given of interfacing LEDs and seven segment displays to the microcontroller. The presentation concludes by mentioning the Keil software used for programming the microcontroller.

4. About the Embedded system
• Embedded system does not look like a computer but like a
computer it has processor, software, input and output.
• Embedded means it build into a system.
• It is a combination of hardware and software to perform a
particular tasks.

5. Categories of Embedded system
 Stand-alone Embedded system.
 Real-time Embedded system.
 Embedded system for network appliances.
 Embedded system for mobile devices

6. Features of Embedded system
• Embedded systems are programmed to do a specific tasks
only.
• It is based on real time operating system.
• Small size and less weight.
• More efficiency.

8. Processors
 It is the central processing unit known as the heart of the
Embedded systems.
 It is the hardware that executes the software and brings life to
the embedded system.
 Controls the activities of all other circuits.
 Embedded system can be divided into two broad categories
microprocessor and microcontroller .

9. Microprocessor
• A silicon chip that contain a CPU, the term microprocessor and
CPU interchangeably.
• It is an 8 bit processor.
• It has multiplexed address and data bus(AD0-AD7).
• It works on 5v dc supply.

10. Microcontroller
 The 8051 is the first microcontroller of the MCS-51 family
introduced by Intel corporation at the end of 1970’s.
 The 8051 has family characteristics:
• 4k bytes ROM
• 128 bytes RAM
• Two timer/counters(16bit)
• Examples Intel’s8051, Motorolla’s6811.

13. Pin description of 8051
• Port 0(P0): Port 0 performs two functions first, low-order
address bus multiplexed to the data bus.
• Port 1(P1): It have no dual functions. It can be used as input
and output.
• Port 2(P2): It may be either used as high-order address bus.
• Port 3(P3): It may be used as input/output port .

17. About the software
• In this system used Keil software. The keil software 8051
developments tools can be used by any level of programmer to
get 8051 microcontroller architecture.
• The procedure for using keil:-
• Create source code then save file if program in assembly.
• Build and translate and lastly correct errors.
