Create a project Lab$2.$circ in the Logisim. Add a circuit testing Registers $($including $1-$bit, $2-$bit, $8-$bit$).$ Add a circuit testing TRI$-$STATE BUFFERS $($including $1-$bit, $2-$bit, $8-$bit$).$ Add a circuit testing Decoders $($including $1$ to $2,2$ to $4,$ and $3$ to $8$ decoders$).$ Add a circuit to build a $1-$bit CPU described in the lab notes. Here is a picture of the $1-$bit CPU circuit for your reference. Some Relevant Details: The ALU performs two operations, XOR and AND. The operation to be performed is determined by the code in the IR$.$ The value $0$ in the IR indicates an XOR operation and the value $1$ in IR indicates an AND operation. The following control signals will be required for our $1-$bit CPU in this lab: ACCout, ACCin, TMPout, TMPin, ALUout, IRin, Bout, Bin, Cout, Cin, EXTin, EXTout. To implement the operation AND, let's assume that it uses the operands in registers B and C$,$ and then stores the result in C$,$ The following instructions would have to be executed. $($assume the external input switch is set to the value $\text{'}1\text{'}-$ the pre$-$condition for the AND operation$)$: Remember to pre$-$load $\text{'}0\text{'}$ in register B and $\text{'}1\text{'}$ in register C$.$ And see what is the result in register C$.1.$ EXTin, EXTout, IRin. $//$ Load $\text{'}1\text{'}$ in register IR for AND operation. $2.$ EXTin, EXTout, Bin. $//$ Load $\text{'}0\text{'}$ in register B$.3.$ EXTin, EXTout, Cin. $//$ Load $\text{'}1\text{'}$ in register C$.4.$ Bout, ACCin. $5.$ Cout, TMPin. $6.$ ALUout, Cin.
