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

*A system is to have the following set of register transfers, implemented using buses:

(a) For each destination register, list all of the source registers.

---

(b) For each source register, list all of the destination registers.

---

(c) With consideration for which of the transfers must occur simultaneously, what is the minimum number of buses that can be used to implement the set of transfers? Assume that each register will have a single bus as its input.

---

(d) Draw a block diagram of the system, showing the registers and buses and the connections between them.
