Microprocessor System Design

Microprocessor System Design: A Practical Introduction describes the concepts and techniques incorporated into the design of electronic circuits, particularly microprocessor boards and their peripherals. The book reviews the basic building blocks of the electronic systems composed of digital (logic levels, gate output circuitry) and analog components (resistors, capacitors, diodes, transistors). The text also describes operational amplifiers (op-amp) that use a negative feedback technique to improve the parameters of the op-amp. The design engineer can use programmable array logic (PAL) to replace standard discrete TTL and CMOS gates in circuits. The PAL is programmable and configurable to match the requirement of a given circuit. Using PAL can save space, a very important factor in the miniaturization process. Examples of PAL applications include the BCD counter, the LS 138 emulator, and a priority interrupt encoder. The book also explains the operation and function of a microprocessor, the bus-based systems, analog-to-digital conversion, and vice-versa. The text is suitable for programmers, computer engineers, computer technicians, and computer instructors dealing with many aspects of computers such as programming, networking, engineering or design.

Microprocessor-Based Control Systems

Recent advances in LSI technology and the consequent availability of inexpensive but powerful microprocessors have already affected the process control industry in a significant manner. Microprocessors are being increasingly utilized for improving the performance of control systems and making them more sophisticated as well as reliable. Many concepts of adaptive and learning control theory which were considered impractical only 20 years ago are now being implemented. With these developments there has been a steady growth in hardware and software tools to support the microprocessor in its complex tasks. With the current trend of using several microprocessors for performing the complex tasks in a modern control system, a great deal of emphasis is being given to the topic of the transfer and sharing of information between them. Thus the subject of local area networking in the industrial environment has become assumed great importance. The object of this book is to present both hardware and software concepts that are important in the development of microprocessor-based control systems. An attempt has been made to obtain a balance between theory and practice, with emphasis on practical applications. It should be useful for both practicing engineers and students who are interested in learning the practical details of the implementation of microprocessor-based control systems. As some of the related material has been published in the earlier volumes of this series, duplication has been avoided as far as possible.
