Abstract

At the heart of a microcomputer system lies the CPU or processor. The processor runs a program by repeatedly fetching and executing instructions from main memory. By using a step-by-step approach, this chapter outlines the way in which this is done using a highly simplified processor. This will provide a foundation for understanding the operation of a real processor in chapter 5.
