1- The block diagram shown below represents the hardware that implements the following microoperations R1 Complementer R2 Adder for the 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 +btg)(a*tbitc))l The simplified complementer expression- Adder-(a'b'ctabc)L. The simplified adder expression- L- (b(a +hbts)(atbtc) +abict abc) The simplified expression for L- The selelction multiplexer switch is S- L- (bata. The sira.kb to)r Theroeatdsignats an
