With a focus on the Intel 8086 family of microprocessorsthat are used in the IBM PCs, Microprocessors and Interfacing teaches students the programming, system connections, and interfacing of microprocessors and theirperipheral devices in detail. This detailed study givesstudents the foundation of knowledge they need to learnabout other microprocessors on their own. The text begins with a brief introduction to computer hardware that leads to an in-depth look at how microprocessor-based computers are programmed to do real tasks. These chapters cover assembly language programming of 8086-based systems. Latter portions of the text discuss all aspects of interfacing, including bus architecture, microcomputer interfaces with input/output devices and systems, A/D and D/A conversion, and operating systems. The use of microprocessor development hardware (including the IBM PC and SDK-86) and study of actual examples of microprocessor-controlled industrial systems are emphasized. Throughout the text, the emphasis is on writing assembly language programs in a top-down, structured manner.
