The document provides an introduction to embedded systems, including a definition and key characteristics. It discusses how embedded systems contain microcontrollers or digital signal processors and are designed to perform specific control functions within larger systems. Examples of embedded systems include appliances, vehicles, and electronic devices. The document highlights how embedded systems are specialized for particular tasks, constrained in terms of components and costs, and must perform functions in real-time.

Summary

4. An embedded system is a computer system designed for
specific control functions within a larger system, often
with real-time computing constraints.
Embedded systems contain processing cores that are
typically either microcontrollers or digital signal
processors (DSP).

5. One of the first recognizably
modern embedded systems
was the Apollo Guidance
Computer, developed
by Charles Stark Draper at
the MIT Instrumentation
Laboratory.
The first microprocessor for
example, the Intel
4004, was designed
for calculators

6. Embedded system: is a system whose principal
function is not computational, but which is
controlled by a computer embedded within it.
The embedded system is a combination of
hardware and software to perform a particular
task.

7. Special-purpose
 Typically, is designed to
execute a single
program, repeatedly
 Tactic and Strategy
Tightly constrained
 Fewer components based
 Low cost
 Simple systems

8. Reactive and real-time
 Reactive: Continually reacts
to external events
 Real-time: Must compute
certain results in real-time
Hardware and software
co-exist
 The software written for
embedded systems is often
called firmware

9. Small size & less weight.
More efficiency.
Embedded systems are programmed to perform
specific task only.
Embedded systems are playing important roles
in our lives every day.

13. Performance:
 Technology Advances
CMOS VLSI dominates older technologies (TTL, ECL)
 Computer architecture improvements
RISC, superscalar, RAID,
Price:
 Simpler development
CMOS VLSI: smaller systems, fewer components
 Higher volumes
CMOS VLSI: same device cost 10,000 vs. 10,000,000 units

16. Performs one or a few pre-defined tasks
Very specific requirements
Task-specific hardware and mechanical parts
Often mass-produced
Design engineers can optimize it

17. High reliable.
Can be interface as user convenient.
Embedded systems are constrained for power
consumption since many embedded systems
work on a battery at low power.

18. A quiet revolution is in progress in the utility
industry.
Static metering devices, have been in use
for the better part of a century
Gradually being replaced with multirate, multifunction meters
Capable of more accurately accounting for
utility usage.
