1- The block diagram shown below represents the hardware that implements the following microoperations (b(a,+D+c)(a+b'+c)): R1 R2 R1 Complementer 0) R2 Adder Where Rland 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.) a- Simplify the control statements for the complementer, adder and the load input (L); Complementer -(b(a+b+c)(a'+b+c))i The simplified complementer expression- Adder-(a b'c+ab'c)L The simplified adder expression- L-(b(a+b+c)(a'+b+c) +ab'c+ ab'c). The simplified expression for L- The selelction multiplexer switch is S
