There are a mind-boggling number of microcontrollers in use today. Hundreds of millions are shipped every year in products such as automobiles and coffee makers. In order to fully understand this technology, it is necessary to grasp current principles of microprocessor technology and theirrelationship to microcontrollers. Microcontrollers and Microcomputers: Principles of Software and Hardware Engineering is a top-down introductory treatment of microprocessors which provides students with an accessible and thorough overview of the key hardware and software engineering issues oftoday. The text begins with an explanation of the mystery of a stored-program computer, and goes on to explore the resources of the processor in a laboratory setting. Cady leads students step-by-step through examples that utilize various instructions. More difficult programming assignments are given asreaders progress. These assignments demonstrate the need for techniques used in debugging, which is a critical step in developing software for microprocessors. A key chapter dedicated to software design presents top down design and promotes pseudocode. Ideal for use in microprocessor courses in electrical engineering and computer science, the text is accompanied by an instructor's manual which includes problem solutions and a course outline.
