- Consider the following instruction:Instruction: Add Rd, Rs, RtInterperation: Reg[Rd] = Reg[Rs] + Reg[Rt] RegWrite MemRead ALUMux MemWrite ALUOp RegMux Branch a, What are the values of control signals generated by the control in Figure 4.2 for the above instruction? b, Which resources (blocks) perform a useful function for this instruction? c, Which resources (blocks) produce outputs, but their outputs are not used for this instruction? d, which resources (blocks) produce no output for this instruction?When we execute a program that contains a lot of if-statements or for/while-loops, the pipelineof Teletraan-2 faces a problem. The instruction fetch stage does not know which branch of theif-statement shall be fetched, until the write back stage writes the True/False value of the ifcondition to a flag register. What should we do to alleviate the problem?A. Don't wait. Let the CPU predict which branch will probably be executed, and fetch theinstruction(s) of that branch. If it is later revealed the prediction is wrong, undo theinstruction(s).B. Don't wait. Fetch-decode-execute the instructions of all branches of the if-statement.C. Nothing. We can only let the instruction fetch stage wait for the write back stage to finishwriting the value of the if-condition.D. Eliminate all if-statements during the assembly process.1. fast please in assembly language You are giving the before condition and an instruction.
