Please read Appendix B of the Patterson & Hennessy text, and be prepared to discuss the following issues:

1. We looked at the datapath of a simple processor last time. Let's add the nasty details: the control and the clocking. Assume that all the state devices (accumulator, registers) are made of edge-triggered D-type flip-flops. Is there a finite-state machine buried somewhere in the control? Does the design need more than one clock signal?

2. What do you think is meant by the cycle time of a computer? What determines the cycle time in our simple processor?
