Microprocessor Interfacing
1st Edition
R E Vears
English
Microprocessor Interfacing provides the coverage of the Business and Technician Education Council level NIII unit in Microprocessor Interfacing (syllabus U86/335). Composed of seven chapters, the book explains the foundation in microprocessor interfacing techniques in hardware and software that can be used for problem identification and solving. The book focuses on the 6502, Z80, and 6800/02 microprocessor families. The technique starts with signal conditioning, filtering, and cleaning before the signal can be processed. The signal conversion, from analog to digital or vice versa, is explained to answer why conversion is necessary for the microcomputer or processor. The types of analogue to digital converter, voltage measurements, scaling, and interfacing with ADC to a microcomputer are all taken into account. After the signal has been converted into readable data, the date transfer techniques are described. For data between systems and subsystems to be efficient, the timing, electrical, I/O lines, serial data, and bus structure should be considered. A more detailed explanation of parallel I/O controllers as applied to Z80 PIO and the 6821 PIA follows. For serial I/O controllers, the serial data transfers, speed in baud rate, software routines, and ASCII codes are all examined. Finally, the dedicated I/O controllers involving keyboard encoding, the ASCII (QWERTY) keyboard interface, the visual display unit, cathode ray tube controller devices, and the drive controllers are discussed, as each of these requires one specific application. This book is useful for computer engineers, software engineers, computer technicians, teachers, and instructors in the field of computing learning. This text can also be an informative reading for those have great interest in computer hardware.

Andrew Colin
English
Programming for Microprocessors deals with the basics of programming for microprocessors and contains practical aids to programming. Topics covered range from assembly language and microprocessor design to the Motorola 6800, programming techniques, control of peripheral devices, and high-level languages. Emphasis is given to the computer-like aspects of microprocessors. This text is comprised of 12 chapters; the first of which provides a general overview of microprocessors, differences between hardwired and programmed devices, and different kinds of microprocessors. The reader is then introduced to the basic types of information inside a microprocessor, including Boolean information, numerical information, character codes, and the machine code. The chapters that follow focus on the intellectual and practical tools that the designer of a microprocessor system will need. The basic structure of a microprocessor is analyzed, with particular reference to a simple hypothetical computer and some programs for this machine. This book also discusses assembly language; some of the features that give microprocessors their flexibility as well as generality and power; and the Motorola 6800 microprocessor as an example of machine architecture. Some programming techniques, high-level languages for writing programs, and the problem of bringing the hardware and software together are highlighted. This book will be useful to computer programmers, computer scientists, and electronic engineers.

Students' Guide to Program Design
1st Edition
Lesley Anne Robertson
English
Students’ Guide to Program Design is a textbook on program design. This textbook approaches program design by using structures programming techniques and pseudocode to develop a solution algorithm. Divided into 10 chapters, the book begins with a basic explanation of structured programming techniques, top-down development, and modular design. This discussion is followed by detailed concepts of the syntax of pseudocode; methods of defining the problem; the application of basic control structures in the development of the solution algorithm; desk checking techniques; hierarchy charts; and module design considerations. Each step in the development of solution algorithms is covered in this book. These steps are defining the problem; grouping of activities into subtask or functions; creating a hierarchy chart; establishing the logic of the mainline of the algorithm; developing each pseudocode for each successive module in the hierarchy chart; and to desk check the solution algorithm. The development of general pseudocode algorithms as used in common business applications is then studied to help student programmers be familiarized with the concept. In program design, the independence of each module, the ease of maintenance, and the cohesive of the particular module with the other modules in the program are all considered as being important. This textbook will serve as a guide for both beginning and experienced programmers who want to solve common business programming problems.
