Provides an introduction to microprocessor systems, their operation and design. The text covers topics needed by engineers and computer scientists who are interested in applying microprocessors in practical situations, such as computer hardware, software, and the design and testing of systems.

The less-experienced engineer will be able to apply Ball's advice to everyday projects and challenges immediately with amazing results. In this new edition, the author has expanded the section on debug to include avoiding common hardware, software and interrupt problems. Other new features include an expanded section on system integration and debug to address the capabilities of more recent emulators and debuggers, a section about combination microcontroller/PLD devices, and expanded information on industry standard embedded platforms. - Covers all 'species' of embedded system chips rather than specific hardware - Learn how to cope with 'real world' problems - Design embedded systems products that are reliable and work in real applications

Since its commercialization in 1971, the microprocessor, a modern and integrated form of the central processing unit, has continuously broken records in terms of its integrated functions, computing power, low costs and energy saving status. Today, it is present in almost all electronic devices. Sound knowledge of its internal mechanisms and programming is essential for electronics and computer engineers to understand and master computer operations and advanced programming concepts. This book in five volumes focuses more particularly on the first two generations of microprocessors, those that handle 4- and 8- bit integers. Microprocessor 4 – the fourth of five volumes – addresses the software aspects of this component. Coding of an instruction, addressing modes and the main features of the Instruction Set Architecture (ISA) of a generic component are presented. Futhermore, two approaches are discussed for altering the flow of execution using mechanisms of subprogram and interrupt. A comprehensive approach is used, with examples drawn from current and past technologies that illustrate theoretical concepts, making them accessible.

C for the Microprocessor Engineer is designed to introduce the reader to the use, problems and advantages of using C as the programming medium for embedded microprocessor systems. It can be used as a general stand-alone text in microprocessor technology, since only a limited background is expected in microprocessor hardware and software. Key Features: written from an engineering point of view rather than taking a traditional software approach; real-world commercial hardware and software products used throughout; comparison between 8-bit (6809) and 16/32-bit (68000) processor made in order to emphasize the portability advantages of a high-level language; introduction of software tools such as relocatable assemblers, linkers, compilers and simulators; and use of a mini-project to bring together, compare and contrast the various concepts introduced in the text.
