shown below represents the hardware that implements the following 9- The block diagram microoperations: (abc'+ abc.); R1 R2. (abe+abc): R1 R1 + R2 R1 Complementer R2 Adder Where R1and R2 are two n-bit registers and a, b, and c are control variables. Include the logic gates for the control functions and multiplexer inputs and outputs. (Remember that the symbol + designates an OR operation in a control or Boolean function but it represents an arithmetic plus in a microoperation.) Simplify the control statements for the complementer, adder and the load input (L); a-Complementer= (abc+ aber The simplified complementer expression b-Adder(abctabOn The simplified adder expression= C-L= (abc't abc' + abc+ abc) The simplified expression for L = d-The selection multiplexer switch is S=
