The plus (+) indicates a more advanced problem and the asterisk (*) indicates that a solution is available on the Companion Website for the text.

*Assume that the transfers with strobing shown in Figure are between a CPU on the left and an I/O interface on the right. There is an address coming from the CPU for each of the transfers, both of which are initiated by the CPU.

Figure Asynchronous Transfer Using Strobing

(a) Draw block diagrams showing the interconnections for the transfers.

---

(b) Draw the timing diagrams for the two transfers, assuming that the address must be applied some time before the strobe becomes 1 and removed some time after the strobe becomes 0.
