Draw the diagram for a circuit which realizes the register transfers below. You are not allowed to use any MUX, you can use tri-state buffers. Your registers should have input, output and clock; you don't need to draw Load and Enable lines on registers, assume that they are always enabled and always loading.

• To save space on your diagram group multiple wires as a bus by drawing a single line with a slash to show that it is a bus, you can write "n" as the number of bits on top of slash.
• Label your pins and wires properly.
• Don't forget to indicate with a dot if two crossing lines are connected to each other.
