I asked the question before and the answer I got does not makes sense. My question is why did not we considered the Adder, Shift, ANd, Control when calculation delay time.?

The input to the control unit is the 7-bit opcode field from the instruction.The outputs of the control unit consist of two 1-bit signals that are used to control multiplexors (ALUSrc and MemtoReg), three signals forcontrolling reads and writes in the register file and data memory (RegWrite, MemRead, and MemWrite), a 1-bit signal used in determiningwhether to possibly branch (Branch), and a 2-bit control signal for the ALU (ALUOP). An AND gate is used to combine the branch controlsignal and the Zero output from the ALU; the AND gate output controls the selection of the next PC. Notice that PCSrc is now a derived signal,rather than one coming directly from the control unit. Thus, we drop the signal name in subsequent figures.
