This book introduces a modern approach to embedded system design, presenting software design and hardware design in a unified manner. 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, controls systems, chip technologies, and modern design tools. For courses found in EE, CS and other engineering departments. Table of Contents Preface. Introduction. Custom Single-Purpose Processors: Hardware. General-Purpose Processors: Software. Standard Single-Purpose Processors: Peripherals. Memory. Interfacing. Digital Camera Example. State Machine and Concurrent Process Models. Control Systems. IC Technology. Design Technology. Appendix A: Online Resources. Index.
