Abstract
General purpose computers are intended to run just one program. The program code is written into a read only memory (ROM) device and thus appears in the computer memory space, ready to run when the computer is powered up. A computer based on a microprocessor such as the G80 is quite adequate for very many embedded systems. This chapter explores how the basic techniques used in the G80 can be extended to make a microprocessor capable of meeting the demands of a modem general-purpose personal computer as found on desks throughout the world. The chapter outlines the history of the development of general-purpose computers. It then illustrates the organization of memory within a computer and introduces the locality of reference properties of a program. Finally, it identifies the major components of an operating system.
