Real-time embedded devices, products, and systems touch every part of our lives. Generally they are unseen, ‘‘buried’’ inside things (Figure 1.1). In spite of their invisibility, people still expect those products to functionfor example, microwave ovens, automobiles, or aircraft with hundreds of microcontrollers and embedded systems. This book introduces various development processes for real-time em-
bedded products; actually, it is more like a ‘‘keyhole’’ view of how some products come to market. It will focus on development processes through examples and case studies. This will hopefully give you a deeper appreciation and understanding how you might go about designing and developing realtime embedded products.
