The book provides guidance and practical techniques for the CPU design and its implementation. By scheduling a complete CPU design procedure into a series practicing tasks, the book offers a step-by-step process support to the readers for the design of a CPU which can run Unix-like OS (e.g. Linux) kernel. It also covers various design practices and debug skills. The book is suitable for undergraduate and graduate students, lecturers and tutors, as well engineers and practitioners who are interested in the CPU design and implementation.
