Re: Any suggestions on how to approach the building of the CPU Chip?
Figure 5.9 in the book has most of the CPU implementation. You need to connect the control signals.
First find all the places which "produce" control signals (hint: they are 2) and all the signals they provide. Then for each controlled block, you need to decide what signal (or signals) control it and how. It's not hard, just think of it piece by piece.
