In today's world, embedded systems are everywhere ,homes, offices, cars, factories, hospitals, plans and consumer electronics. Their huge numbers and new complexity call for a new design approach, one that emphasizes high-level tools and hardware/software tradeoffs, rather than low-level assembly-language programming and logic design
It covers trends and challenges, introduces the design and use of single-purpose processors ("hardware") and general-purpose processors ("software"), describes memories and buses, illustrates hardware/software tradeoffs using a digital camera example, and discusses advanced computation models, control systems, chip technologies, and modern design tools
Embedded systems engineer is a relatively new job classification that merges electrical engineering and computer science. These computer engineers work on hardware and software designs for electronic medical equipment, industrial and military control systems, mobile communications devices, appliances, and remote controls. They need at least a bachelor's degree in a relevant field, and some schools now offer certificate and undergraduate and graduate degree programs in embedded systems engineering.
