This textbook for courses in Digital Systems Design introduces students to the fundamental hardware used in modern computers. Coverage includes both the classical approach to digital system design (i.e., pen and paper) in addition to the modern hardware description language (HDL) design approach (computer-based). Using this textbook enables readers to design digital systems using the modern HDL approach, but they have a broad foundation of knowledge of the underlying hardware and theory of their designs. This book is designed to match the way the material is actually taught in the classroom. Topics are presented in a manner which builds foundational knowledge before moving onto advanced topics. The author has designed the presentation with learning goals and assessment at its core. Each section addresses a specific learning outcome that the student should be able to \"do\" after its completion. The concept checks and exercise problems provide a rich set of assessment tools to measure student performance on each outcome. 200 Tables, color; 445 Illustrations, color; 51 Illustrations, black and white; XVI, 485 p. 496 illus., 445 illus. in color.
