An embedded system is a combination of hardware and software designed for a specific task. It is made up of a processor, memory, input/output devices, and application software. Embedded systems are used in devices like household appliances, medical equipment, vehicles, and more. They are designed to perform dedicated functions in real-time, making them more reliable, efficient, and cost-effective than general purpose computers. Common processors used in embedded systems include Intel 8051 and ARM. Development tools include assemblers, compilers, debuggers, and simulators.

1. EMBEDDED SYSTEM

2. INTRODUCTION
 Embedded system is the combination of
hardware and software which is design for a
specific task.
 An Embedded system can also be defined as
a single purpose computer.
 Every device which is intelligent is because
the role of Embedded System.

3. COMPONENTS OF EMBEDDED SYSTEM
 It has Hardware
Processor,Timer, Interrupt controller, I/O Devices,
Memories, Ports , Motors etc.
 It has main Application Software
Which may perform concurrently the series of task or
multiple tasks.
 It has RealTime Operating System(RTOS).

11. EMBEDDED SYSTEM EXAMPLES

12. EMBEDDED VERSUS GENERAL PURPOSE
SYSTEM
Embedded system General purpose system
Few applications. Board class of applications.
A part of a bigger system. Standalone or integrated in
parallel with other system.
Not programmed by end
user.
End user programmable.
Harder to develop. Easier to develop.
