Please help!

1- The block diagram shown below represents the hardware that implements the following microoperations: 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+btc(a'+b+c)l The simplified complementer expression- Adder-(a'b'ctab'c)L. The simplified adder expression - L-(b(a +b+c)(a'+b'+c) + a b'ct ab'c). The simplified expression for L- The selelction multiplexer switch is S- ac' b'c
