with real-time computing
1. INTRODUCTION OF EMBEDDED SYSTEM
It is embedded as
part of a complete
devices in common

2. USES OF EMBEDDED SYSTEM
3. 8051 MICROCONTROLLER
A microcontroller is an economical
computer-on-a-chip for doing with
specific tasks, such as displaying or
receiving information through LED or
remote controlled devices.
The 8051 is an 8-bit microcontroller
which means that most available
operations are limited to 8 bits
6.FEATURES OF 8051
i. RAM – 128 Bytes (Data memory)
ii. ROM – 4Kbytes (ROM signify the on – chip program space)
iii. 32 general purpose registers each of 8 bits
iv. Two 16 bit Timer/ Counter
v. Input/output Pins – 4 Ports of 8 bits each on a single chip.
vi. 3 internal and 2 external interrupts.
vii. 8 – bit ALU (Arithmetic Logic Unit)
An interrupt is a communicated
to the controller, by a hardware
device or software, on receipt of
which controller momentarily
stops and responds to the
Software, is a collection of
computer programs and related data
that provide the instructions for
telling a computer what to do and
how to do it.

USE OF COMPILER AND PROGRAMMER
Programming Tool: ISP
1.Double Click on the icon present on the desktop.
2.The following window will be popped-up
9. Write or copy your code there & save it with extension .c
or .asm depending on your coding.
2)Go to target & then source group, right click on there &
click on the option add files to the project.
Select your asm or c file which you want to add.
3)Go to the option for target, click on output &tick on create
hex file option
4)Now build target.(Click on the pointed option)...
5) It will show you 0 errors &0 warning on Output Window.
