Suppose that a particular operation that the Simple Computer datapath can performed is described by the following datapath control word:

DAAABAMBFSMDRWMW$10101111011100010$

The following questions are asking about this operation being performed.

$$

Which register supplies the value of Operand A$?[$ Select $]["$R$0","$R$1","$R$2","$R$3","$R$4","$R$5","$R$6","$R$7"]$

Which register supplies the value of Operand B$?[$ Select $]["$R$0","$R$1","$R$2","$R$3","$R$4","$R$5","$R$6","$R$7"]$

Which value actually reaches Bus B$,$ to serve as a Function Unit operand and Memory Write data $?[$ Select $]["$The value from the register chosen as Operand B$.",$ "The "Constant In$"$ value.", "Neither of these values."$]$

Which operation does the Function Unit perform on the values that reach it$?[$ Select $]["$Transfer A $($F $<-$ A$)",$ "Increment A $($F $<-$ A $+1)",$ "Add $($F $<-$ A $+$ B$)",$ "Add and Increment $($F $<-$ A $+$ B $+1)",$ "Subtract and Decrement $($F $<-$ A $+$ B$\text{'})",$ "Subtract $($F $<-$ A $+$ B$\text{'}+1)",$ "Decrement A $($F $<-$ A $-1)",$ "AND $($F $<-$ A AND B$)","$OR $($F $<-$ A OR B$)",$ "XOR $($F $<-$ A XOR B$)",$ "Complement A $($F $<-$ A$\text{'})",$ "Transfer B $($F $<-$ B$)",$ "Shift Right B $($F $<-$ sr B$)",$ "Shift Left B $($F $<-$ sl B$)",$ "The Function Unit does not perform any of these operations."$]$

$($Since I can't make these symbols in the answer fields, recall that$$is the AND operation,$$is the OR operation, and$$is the XOR operation.$)$

Which value actually reaches$$Bus D$,$ so that it can possibly be stored in the Register File? $[$ Select $]["$The output of the Function Unit.", "The "Data In$"$ value.", "Neither of these values."$]$

Which register is selected as the destination register $?[$ Select $]["$R$0","$R$1","$R$2","$R$3","$R$4","$R$5","$R$6","$R$7"]$

Does the register chosen as the destination$$actually receive the value$$from Bus D on the clock edge that follows the operation? $[$ Select $]["$Yes$,$ a register write occurs because of the specified control word.", $"$No$,$ a register write does not occur because of the specified control word.", "There is not enough information to determine if a register write occurs because of the specified control word."$]$
