As the title suggests, microprogramming is a secondary topic in the general treatment of "Computer Organization" in this text. (One is reminded of the discussion at the closing session of Micro-5 about whether microprogramming is a viable subject of inquiry of itself.) I do not mean to suggest that Professor Chu has simply added the name of a "hot topic" to the title of his book and then given it shallow treatment. Two of the eleven chapters deal entirely with microprogramming, and the chapter on Control Organization contains a good section of the hows and whys of microprogramming. Furthermore, the independent control points (control signals) of computer structures are referred to as "micro-operations" throughout the book. This terminology automatically stresses the proper role of microprogramming as one of the possible techniques for implementing the control function of a processor. In addition, the author's Computer Design Language (CDL) is built around the symbolic representation of these micro-operations, providing good continuity throughout the material presented.
