Ebook: Digital Logic and Microprocessor Design with VHDL

The author states, in Chapter 1:
"In this book, I will show you from the ground up how to design the digital circuits inside the PC, or more precisely, the circuitry inside those black IC chips. Specifically, I will show you how to design the logic circuit for a microprocessor, which is at the heart of every electronic device."

This is exactly what he does, step by step. There is sample code and a recommended development board that you can purchase for nominal cost to learn from. I am so glad this book is available and I am writing this review to encourage authors like this to continue. Interested people, hobbyists and professional engineers alike, will enjoy this walk through the mysterious world of IC chips.

This is the best guide on the subject I have seen so far.
