Digital Logic and Microprocessor Design with Interfacing Second Edition by Enoch Hwang.
This book teaches you how to put these two types of circuits together to form both dedicated and general-purpose microprocessors. This book's unique approach combines the use of logic principles with the building of individual components to create data paths and control units. With this book you are able to design simple microprocessors, implement them in real hardware, and interface them to real-world devices.
