Question the ALU control takes 2 bits input from the Control that controls the OP code, how does it handles the operations that needs the funct code to be obtained??
Answer, The ALU control has another input which is the instruction bits 0 - 5. it takes these 6 bits with the two ALUOp bits and generate the required signal for the ALU as shown in figures 5.12 and 5.13
