Draw the diagram for circuit which realizes the register transfers below. You are not allowed to use MUX. You can use tri-state buffers. Use registers with clock, load and enable inputs (see image below, if it isn't visible see register.png). To save space, on your diagram use a single arrow to represent all data inputs of a register (by putting a slash and a number on top of the arrow to show that it is a multi-wire bus as seen on the image below) and also use single arrow to represent all data outputs.
