•
Designed for heavy user
interaction.
•
Uses a variety of peripherals
(displays, keyboards, mice,
internet connections, wireless
communication capability).
•
Expensive ($100s - $1000s).
•
Use a group of integrated
circuits or chips (ICs).
•
One implements the
central processing unit
(CPU).
•
Several implement data
memory and program
storage.
•
Possesses a
distributed
architecture (full functionality of
the computer is spread across
multiple IC chips).

•
Resources can be
implemented on a single
IC.
•
Include a variety of
peripherals (timers,
analog-to-digital
converters, digital-to-
analog converters, serial
interfaces).
•
Small size makes them
very versatile.

•
Contains firmware (only
the
needed
software
which is not intended to
be changed frequently).
•
May contain Real Time
Operating Systems
(RTOS) which are used
as a task scheduler.
•
Low cost (10s of cents to
a few dollars).

Embedded Systems Design, Chapter 1 provides an insightful overview of embedded systems, distinguishing them from general-purpose computers. The chapter delves into the characteristics of embedded systems, their design considerations, and the various types of embedded computers such as general-purpose computers and embedded computers. It highlights the differences in functionality, architecture, and cost between embedded systems and general-purpose computers. The chapter also emphasizes the significance of real-time operating systems (RTOS) in embedded systems and the role of firmware in these systems.
