Chapter 1

The embedded and real-time space


This chapter introduces concepts of embedded and real-time programming and shows how Linux fits in. We point out that embedded systems are often resource constrained, and use unusual peripheral devices not often found in PCs. Real-time means that the system must respond to its environment in a predictable time, not necessarily fast, but predictable.
