INTRODUCTION HISTORY ARCHITECTURE OF EMBEDDED SYSTEM APPLICATION’S ESSENCIAL COMPONENTS STRUCTURE CLASSIFICATION CONCLUSION
WHAT IS EMBEDDED SYSTEM? An Embedded System is a microprocessor based system that is embedded as a subsystem, in a larger system (which may or may not be a computer system).

HISTORY • First embedded system was made in MIT instrumentation library,usa. • Many type of gates were used • For only small applications
Application areas • Automative electronics
• Aircraft electronics
• Trains
• Telecommunications
Application areas • Medical systems
• Military applications
• Authentication
Application areas • Consumer electronics • Fabrication equipment
• Smart buildings
Essential Components • Microprocessor / DSP • Actuators • Memory (On-chip and Off chip)
• Converters (A-D and D-A) • Sensors
• Communication path with the interacting environment

Essential Considerations • • • • •
Response Time Area Cost Low Power (Battery Life) Reliability
Fault Tolerance
General Characteristics of Embedded Systems • Perform a single task • Increasingly high performance and real time constrained • Power, cost and reliability are important considerations • HW-SW systems – Software is used for more features and flexibility – Hardware (processors, ASICs, memory etc. are used for performance and security
Classification of Embedded Systems • Stand alone Embedded system • Real time Embedded system • Networked information appliances • Mobile devices
Stand alone embedded system • Performs only one task(specific) • example1.LCD,LED systems,TV remote system etc.
Real time systems • 1.Soft Real Time • 2.Hard Real Time
Networking Information Appliances • Networking
Mobile System • PDA • Mobile systems • Video Games
Importance of Embedded Software and Embedded Processors • “... the New York Times has • estimated that the average • American comes into contact with about 60 micro-processors every day....” [Camposano, 1996]
Latest top-level BMWs contain over 100 microprocessors [Personal communication]
Most of the functionality of embedded systems will be implemented in software!
CONCLUSION • Now a days the role embedded systems is formal • Es makes the tasks simple • Es is growing as the technology grows
