Knowledge: A little light expels much darkness _ Bahya ibn Paquda, Duties of the Heart During the early 1970s digital computer techniques concentrated on the computational and interfacing aspects of digital systems and the decade began as the age of both the mainframe computer and the minicomputer. Engineers and system designers needed to know the fundamentals of computer operation and how the practical limitations of the architectures of the day, the memory size, cost and performance could be overcome; it was for this reason that this book was first written. By 1980 the microprocessor revolution had arrived. As a result the microprocessor became a component of a system, rather than a system itself, and the need to understand the behaviour of the device became of even greater importance to the system designer. New developments in mainframe computers were few, with networks of minicomputers taking over their role in many instarices. The 1980 revision of this book took into account the major advances in semiconductor technology that had occurred since it was first published in 1972, and included material relevant to the microprocessor.

Digital Computer Design: Logic, Circuitry, and Synthesis focuses on the logical structure, electronic realization, and application of digital information processors. The manuscript first offers information on numerical symbols, fundamentals of computing aids, quantization, representation of numbers in an electronic digital computer, and computer applications. The text then ponders on the nature of automatic computation and Boolean algebra. Discussions focus on the advantages of a Boolean algebraic description of a digital computer; clock pulse generators and timing circuits; sequential switching networks; elements of information processing systems and types of digital computers; and automatic sequencing methods. The book elaborates on circuit descriptions of switching and storage elements and large capacity storage systems. Topics include static magnetic storage, dynamic delay line storage, cathode-ray storage, vacuum tube systems of circuit logic, and magnetic core systems of circuit logic. The publication also examines the system design of GP computers, digital differential analyzer, and the detection and correction of errors. The text is a valuable source of data for mathematicians and engineers interested in digital computer design.

This textbook covers digital design, fundamentals of computer architecture, and assembly language. The book starts by introducing basic number systems, character coding, basic knowledge in digital design, and components of a computer. The book goes on to discuss information representation in computing; Boolean algebra and logic gates; sequential logic; input/output; and CPU performance. The author also covers ARM architecture, ARM instructions and ARM assembly language which is used in a variety of devices such as cell phones, digital TV, automobiles, routers, and switches. The book contains a set of laboratory experiments related to digital design using Logisim software; in addition, each chapter features objectives, summaries, key terms, review questions and problems. The book is targeted to students majoring Computer Science, Information System and IT and follows the ACM/IEEE 2013 guidelines. • Comprehensive textbook covering digital design, computer architecture, and ARM architecture and assembly • Covers basic number system and coding, basic knowledge in digital design, and components of a computer • Features laboratory exercises in addition to objectives, summaries, key terms, review questions, and problems in each chapter
