Design a $5-$bit information processing unit in Logisim to perform all arithmetic operations. A block diagram of an $8-$bit information processing unit for your reference is shown in the figure.

The description of the processing unit is as follows: The memory unit consists of three registers, and the processor unit consists of three registers$-$R$1,$ R$2,$ and R$3.$ The digital logic circuits manipulate the bits of R$1$ and R$2$ and transfer into R$3$ equal to their arithmetic operation. The information stored in memory registers $($operands $1$ and $2)$ can be transferred to processor registers, and the results obtained in processor registers can be transferred back into a memory register for storage until needed again.
