In order to come up with a reasonably optimized result when designing a hardware interface for a microprocessor or a specialized application, a designer must be quite knowledgeable and constantly keep abreast of new developments. Not only must he master traditional methods used for logic systems but he must also be familiar with a wide range of solutions and a technology which never stops progressing. The CMOS and TTL integrated circuit families include the basic bricks used to build an interface, although prefabricated modules of various sizes may improve the performance/price ratio. Programmable networks (PLD, PAL ®, GAL ®, etc.) are becoming more and more diversified and gate arrays can justifiably be used for smaller and smaller series. When signals work on low frequencies, they can be read or activated by an appropriately programmed microcontroller, which may work out cheaper than wired logic. Therefore, engineers must never stop improving their knowledge and questioning the developing techniques which they learnt to master and which have proved reliable. This book does not only deal with digital circuits, although the basic idea is to interconnect functional blocks only through logic connections. The word interface here really refers to an interface between a microproces.

Most programmers' fear of user interface (UI) programming comes from their fear of doing UI design. They think that UI design is like graphic design—the mysterious process by which creative, latte-drinking, all-black-wearing people produce cool-looking, artistic pieces. Most programmers see themselves as analytic, logical thinkers instead—strong at reasoning, weak on artistic judgment, and incapable of doing UI design. In this brilliantly readable book, author Joel Spolsky proposes simple, logical rules that can be applied without any artistic talent to improve any user interface, from traditional GUI applications to websites to consumer electronics. Spolsky's primary axiom, the importance of bringing the program model in line with the user model, is both rational and simple. In a fun and entertaining way, Spolky makes user interface design easy for programmers to grasp. After reading User Interface Design for Programmers, you'll know how to design interfaces with the user in mind. You'll learn the important principles that underlie all good UI design, and you'll learn how to perform usability testing that works.

Many computer applications require microprocessors to reliably interconnect and communicate with other peripherals in order to perform their intended functions. Interface design, which includes the development of the methods and processes by which two or more components communicate, is a crucial step in the deployment of microprocessors in an embedded computing environment. ARM-based microprocessors are a leading technology in this field, offering a wide range of performance for different applications. This book provides a comprehensive treatment of interface design from basic logical and theoretical principles to practical implementation on an ARM-based microprocessor, addressing both hardware and software considerations. The microprocessor’s high level of complexity is carefully analysed in the text to provide clear guidance for the reader in the design of new applications, resulting in an invaluable reference resource for graduates and engineers involved in the design of electronic products and systems. Key Features: Brings together aspects of digital hardware, interface design and software integration in a single text to make clear the link between low and high level languages for interface control Categorises interface techniques into easily distinguished chapters, progressively involving greater complexity, enabling the reader to quickly find relevant material for a particular application Provides many practical C-coded examples showing both the preparation and use of complex programmable subsystems implemented in a typical commercial product Presents in each chapter an introduction to the essential theoretical aspects and the development of simple interface designs using basic logical building blocks

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.
