The microprocessor industry is divided into the computer and embedded sectors. Both computer and embedded microprocessors share aspects of computer design, instruction set architecture, organization, and hardware. The term “computer architecture” is used to describe these fundamental aspects and, more directly, refers to the hardware components in a computer system and the flow of data and control information among them. In this chapter, various types of microprocessors will be described, fundamental architecture mechanisms relevant in the operation of all microprocessors will be presented, and microprocessor industry trends discussed.
