Design a $$Tripler$.$ Start with the parallel adder with accumulator below.

The idea is that whatever number we load into the y$$s $($e$.$g$.$ y$4$ y$3$ y$2$ y$1$ y$0=00110),$ the output

x$4$ x$3$ x$2$ x$1$ x$0$ should be three times the value of y$.$ Indicate what signals to apply to Ad and ClrN to

produce this result. Note there could be some old data stored in the register. $(10$ marks$)$
