406 CHAPTER 8 Networks

Several interconnect networks have been developed especially for distributed

embedded computing:

■ The I

C bus is used in microcontroller-based systems.

■ The Controller Area Network (CAN) bus was developed for automotive

electronics. It provides megabit rates and can handle large numbers of devices.

■ Ethernet and variations of standard Ethernet are used for a variety of control

applications.

In addition, many networks designed for general-purpose computing have been

put to use in embedded applications as well.

In this section, we study some commonly used embedded networks, includ-

ing the I
